Apache hive error Merging of credentials not suppo

问题:

I am using hadoop 1.2.1, hbase 0.94.14 and hive 1.0.0. There are three datanodes in my clsuter and three regionservers also. I have to import some data from hbase to hive. I have configured hive successfully but when I ran a command to count no. of rows in hive table, its gives following

ERROR [main]: exec.Task (SessionState.java:printError(833)) - Job Submission failed with exception 'java.lang.RuntimeException(java.io.IOException: Merging of credentials not supported in this version of hadoop)'
java.lang.RuntimeException: java.io.IOException: Merging of credentials not supported in this version of hadoop

    at org.apache.hadoop.hive.ql.plan.MapWork.configureJobConf(MapWork.java:540)

I have changed version of hive to 0.14 but same error. What is the solution of it? Note: I cannot upgrade hadoop.

Although your version of Hive is current, this is not the source of your error. You need to upgrade your Hadoop version, to 2.4.0 or above.

The error originates from here https://github.com/apache/hive/blob/3b6825b5b61e943e8e41743f5cbf6d640e0ebdf5/shims/0.20S/src/main/java/org/apache/hadoop/hive/shims/Hadoop20SShims.java#L579
