Subject [jira] [Created] (HBASE-8202) MultiTableOutputFormat should support hbase.mapred.output.quorum
Date Wed, 27 Mar 2013 17:41:15 GMT
Ted Yu created HBASE-8202:
-----------------------------

             Summary: MultiTableOutputFormat should support hbase.mapred.output.quorum
                 Key: HBASE-8202
                 URL: https://issues.apache.org/jira/browse/HBASE-8202
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu


This was brought up by David Koch in thread 'hbase.mapred.output.quorum ignored in Mapper
job with HDFS source and HBase sink' where he wanted to import a file on HDFS from one cluster
A (source) into HBase
tables on a different cluster B (destination) using a Mapper job with an
HBase sink.

Here is my analysis:

MultiTableOutputFormat doesn't extend TableOutputFormat:
{code}
public class MultiTableOutputFormat extends OutputFormat<ImmutableBytesWritable, Mutation>
{
{code}
Relevant configuration w.r.t. output quorum is setup in TableOutputFormat#setConf():
{code}
  public void setConf(Configuration otherConf) {
    this.conf = HBaseConfiguration.create(otherConf);
    String tableName = this.conf.get(OUTPUT_TABLE);
    if(tableName == null || tableName.length() <= 0) {
      throw new IllegalArgumentException("Must specify table name");
    }
    String address = this.conf.get(QUORUM_ADDRESS);
    int zkClientPort = conf.getInt(QUORUM_PORT, 0);
    String serverClass = this.conf.get(REGION_SERVER_CLASS);
    String serverImpl = this.conf.get(REGION_SERVER_IMPL);
    try {
      if (address != null) {
        ZKUtil.applyClusterKeyToConf(this.conf, address);
      }
{code}
