# SeaweedFS Hadoop2 Client
|
||||
|
||||
Hadoop FileSystem implementation for SeaweedFS, compatible with Hadoop 2.x/3.x.
|
||||
|
||||
## Building
|
||||
|
||||
```bash
|
||||
mvn clean install
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
This project includes two types of tests:
|
||||
|
||||
### 1. Configuration Tests (No SeaweedFS Required)
|
||||
|
||||
These tests verify configuration handling and initialization logic without requiring a running SeaweedFS instance:
|
||||
|
||||
```bash
|
||||
mvn test -Dtest=SeaweedFileSystemConfigTest
|
||||
```
|
||||
|
||||
### 2. Integration Tests (Requires SeaweedFS)
|
||||
|
||||
These tests verify actual FileSystem operations against a running SeaweedFS instance.
|
||||
|
||||
#### Prerequisites
|
||||
|
||||
1. Start SeaweedFS with default ports:
|
||||
```bash
|
||||
# Terminal 1: Start master
|
||||
weed master
|
||||
|
||||
# Terminal 2: Start volume server
|
||||
weed volume -mserver=localhost:9333
|
||||
|
||||
# Terminal 3: Start filer
|
||||
weed filer -master=localhost:9333
|
||||
```
|
||||
|
||||
2. Verify services are running:
|
||||
- Master: http://localhost:9333
|
||||
- Filer HTTP: http://localhost:8888
|
||||
- Filer gRPC: localhost:18888
|
||||
|
||||
#### Running Integration Tests
|
||||
|
||||
```bash
|
||||
# Enable integration tests
|
||||
export SEAWEEDFS_TEST_ENABLED=true
|
||||
|
||||
# Run all tests
|
||||
mvn test
|
||||
|
||||
# Run specific test
|
||||
mvn test -Dtest=SeaweedFileSystemTest
|
||||
```
|
||||
|
||||
### Test Configuration
|
||||
|
||||
Integration tests can be configured via environment variables or system properties:
|
||||
|
||||
- `SEAWEEDFS_TEST_ENABLED`: Set to `true` to enable integration tests (default: false)
|
||||
- Tests use these default connection settings:
|
||||
- Filer Host: localhost
|
||||
- Filer HTTP Port: 8888
|
||||
- Filer gRPC Port: 18888
|
||||
|
||||
### Running Tests with Custom Configuration
|
||||
|
||||
To test against a different SeaweedFS instance, modify the test code or use Hadoop configuration:
|
||||
|
||||
```java
|
||||
conf.set("fs.seaweed.filer.host", "your-host");
|
||||
conf.setInt("fs.seaweed.filer.port", 8888);
|
||||
conf.setInt("fs.seaweed.filer.port.grpc", 18888);
|
||||
```
|
||||
|
||||
## Test Coverage
|
||||
|
||||
The test suite covers:
|
||||
|
||||
- **Configuration & Initialization**
|
||||
- URI parsing and configuration
|
||||
- Default values
|
||||
- Configuration overrides
|
||||
- Working directory management
|
||||
|
||||
- **File Operations**
|
||||
- Create files
|
||||
- Read files
|
||||
- Write files
|
||||
- Append to files
|
||||
- Delete files
|
||||
|
||||
- **Directory Operations**
|
||||
- Create directories
|
||||
- List directory contents
|
||||
- Delete directories (recursive and non-recursive)
|
||||
|
||||
- **Metadata Operations**
|
||||
- Get file status
|
||||
- Set permissions
|
||||
- Set owner/group
|
||||
- Rename files and directories
|
||||
|
||||
## Usage in Hadoop
|
||||
|
||||
1. Copy the built JAR to your Hadoop classpath:
|
||||
```bash
|
||||
cp target/seaweedfs-hadoop2-client-*.jar $HADOOP_HOME/share/hadoop/common/lib/
|
||||
```
|
||||
|
||||
2. Configure `core-site.xml`:
|
||||
```xml
|
||||
<configuration>
|
||||
<property>
|
||||
<name>fs.seaweedfs.impl</name>
|
||||
<value>seaweed.hdfs.SeaweedFileSystem</value>
|
||||
</property>
|
||||
<property>
|
||||
<name>fs.seaweed.filer.host</name>
|
||||
<value>localhost</value>
|
||||
</property>
|
||||
<property>
|
||||
<name>fs.seaweed.filer.port</name>
|
||||
<value>8888</value>
|
||||
</property>
|
||||
<property>
|
||||
<name>fs.seaweed.filer.port.grpc</name>
|
||||
<value>18888</value>
|
||||
</property>
|
||||
</configuration>
|
||||
```
|
||||
|
||||
3. Use SeaweedFS with Hadoop commands:
|
||||
```bash
|
||||
hadoop fs -ls seaweedfs://localhost:8888/
|
||||
hadoop fs -mkdir seaweedfs://localhost:8888/test
|
||||
hadoop fs -put local.txt seaweedfs://localhost:8888/test/
|
||||
```
|
||||
|
||||
## Continuous Integration
|
||||
|
||||
For CI environments, tests can be run in two modes:
|
||||
|
||||
1. **Configuration Tests Only** (default, no SeaweedFS required):
|
||||
```bash
|
||||
mvn test -Dtest=SeaweedFileSystemConfigTest
|
||||
```
|
||||
|
||||
2. **Full Integration Tests** (requires SeaweedFS):
|
||||
```bash
|
||||
# Start SeaweedFS in CI environment
|
||||
# Then run:
|
||||
export SEAWEEDFS_TEST_ENABLED=true
|
||||
mvn test
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Tests are skipped
|
||||
|
||||
If you see "Skipping test - SEAWEEDFS_TEST_ENABLED not set":
|
||||
```bash
|
||||
export SEAWEEDFS_TEST_ENABLED=true
|
||||
```
|
||||
|
||||
### Connection refused errors
|
||||
|
||||
Ensure SeaweedFS is running and accessible:
|
||||
```bash
|
||||
curl http://localhost:8888/
|
||||
```
|
||||
|
||||
### gRPC errors
|
||||
|
||||
Verify the gRPC port is accessible:
|
||||
```bash
|
||||
# Should show the port is listening
|
||||
netstat -an | grep 18888
|
||||
```
|
||||
|
||||
## Contributing
|
||||
|
||||
When adding new features, please include:
|
||||
1. Configuration tests (no SeaweedFS required)
|
||||
2. Integration tests (with SEAWEEDFS_TEST_ENABLED guard)
|
||||
3. Documentation updates
