i am executing the hive query but when i do so i ma getting below error :
java.sql.SQLException: Error while processing statement: FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.tez.TezTask. Vertex failed, vertexName=Map 8, vertexId=vertex_1530387194612_0030_4_00, diagnostics=[Vertex vertex_1530387194612_0030_4_00 [Map 8] killed/failed due to:ROOT_INPUT_INIT_FAILURE, Vertex Input: tbtbotabel_db2_orc initializer failed, vertex=vertex_1530387194612_0030_4_00 [Map 8], java.io.IOException: java.util.concurrent.ExecutionException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.token.SecretManager$InvalidToken): token (HDFS_DELEGATION_TOKEN token 214816 for hive) can't be found in cache
I can see error is because of HDFS_DELEGATION_TOKEN for hive can not be found
what are the resoluton steps and what lead to this issue ?
Hi Sandeep ,
Thanks for your response , but could you please explain what is the root cause of this issue , since from the falcon user also I tried to read hdfs and I was getting the same issue as I am doing this from hive user . however in falcon reading hdfs through webhdfs had solved the issue . I was creating a falcon cluster entity from falcon cli .
I wanted to understand the root cause because I am experiencing the same issue from different users as well.
Thanks in Advance.
