Subject HBASE Region server failing to start after Kerberos is enabled
Date Fri, 26 Jun 2015 17:48:18 GMT
HI All,

The region servers failing to start, after Kerberos is enabled, with below error.
Hadoop -2.6.0
HBase-0.98.4

2015-06-24 15:58:48,884 DEBUG [RS_OPEN_META-mdcthdpdas06lp:60020-0] regionserver.HRegion:
Registered coprocessor service: region=hbase:meta,,1 service=AuthenticationService
2015-06-24 15:58:48,886 INFO  [RS_OPEN_META-mdcthdpdas06lp:60020-0] coprocessor.CoprocessorHost:
System coprocessor org.apache.hadoop.hbase.security.token.TokenProvider was loaded successfully
with priority (536870911).
2015-06-24 15:58:48,894 DEBUG [RS_OPEN_META-mdcthdpdas06lp:60020-0] regionserver.HRegion:
Registered coprocessor service: region=hbase:meta,,1 service=SecureBulkLoadService
2015-06-24 15:58:48,907 ERROR [RS_OPEN_META-mdcthdpdas06lp:60020-0] coprocessor.CoprocessorHost:
The coprocessor org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint threw an unexpected
exception
java.lang.IllegalStateException: Failed to get FileSystem instance

I see below properties are included in hbase-site.xml file

<property>
      <name>hbase.coprocessor.region.classes</name>
      <value>org.apache.hadoop.hbase.security.token.TokenProvider,org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint,org.apache.hadoop.hbase.security.access.AccessController</value>
    </property>

<property>
      <name>hbase.bulkload.staging.dir</name>
      <value>/apps/hbase/staging</value>
    </property>


I deleted org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint from the hbase.coprocessor.region.classes
and tried to start. It worked.
I think SecureBulkLoad is causing the problem.

Please help to come over this issue. I would like to have SecureBulkLoad class.

Thanks,
Venkat
