> 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}
