Description

When I try to connect HBase client via TAJO, TAJO cannot connect HBase with below logs.

INFO org.apache.hadoop.hbase.client.RpcRetryingCaller: Call exception, tries=10, retries=35, retryTime=68306ms, msg=row 'lineitem,,' on table 'hbase:meta' at region=hbase:meta,,1.1588230740, hostname=<address>,60020,1450062494778, seqNum=0

...

org.apache.hadoop.hbase.client.RpcRetryingCaller@5b5e2d4c, java.io.IOException: com.google.protobuf.ServiceException: java.lang.NoClassDefFoundError: com/yammer/metrics/core/Gauge

But, I can connect HBase using TestHBaseTable.

I found out that tsql can connect hbase client with appending HBASE_LIB/HBase-hadoop2-compat-*.jar to classpath in bin/tajo.
But, HBase-hadoop2-compat-*.jar has lots of dependency so I try to find out necessity for TAJO in this jar.

HBASE_LIB/metrics-core-*.jar is answer.
I test hbase 0.98.16.1-hadoop2 version with TAJO, builded with manually-configured Hbase version.
