Error ERROR security UserGroupInformation PriviledgedActionException as root auth SIMPLE

Question

While I was using SQOOP: MySQL to HIVE:

/sqoop-1.4.4# bin/sqoop import --connect jdbc:mysql://localhost:3306/hadoop --table csurvey --target-dir /sqoop-hive --hive-import --split-by pname --hive-table csurveysu -username root -P 

While working with the command I got the error above. Can anyone tell how can I solve it?

Hey,

For me, my Hadoop NameNode was in safe mode. That is a read-only mode for the HDFS cluster. It can't Write, until enough datanode up for replication After started up enough datanode still my NameNode in safe mode, just manually OFF safe mode by

root@localhost:/opt/hadoop-2.2.0# bin/hadoop dfsadmin -safemode leave

Just check the inconsistency of HDFS cluster by

[bin]#root@localhost:/opt/hadoop-2.2.0# bin/hadoop fsck /
