org.apache.hadoop.ipc.StandbyException occurs at the thirty of per hour in standby NN
hello, All
Installed 2 NN and 3 DN in my hadoop-2.2.0 cluster,and implemented HDFS HA
with QJM. Currently, looking at the log of standby NN ,it throws below
exception at a regular interval, one hour:
2014-01-24 03:30:01,245 ERROR
org.apache.hadoop.security.UserGroupInformation: PriviledgedActionException
as:ubuntu (auth:SIMPLE) cause:org.apache.hadoop.ipc.StandbyException:
Operation category READ is not supported in state standby
Actually, the active NN is working ,and no applications access HDFS with
error.
Does anyone know what the problem is ?
Thanks,
Francis.Hu

Hi Francis,
This is a non-worry, but you're basically hitting
https://issues.apache.org/jira/browse/HDFS-3447. A temporary
workaround could be to disable the UGI at the logging configuration
level.
