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