Subject Re: All region server died due to "Parent directory doesn't exist"
Date Wed, 19 Feb 2014 06:31:33 GMT
Hi

according to the log message:

1343 2014-02-18 01:19:10,132 ERROR
org.apache.hadoop.security.UserGroupInformation: PriviledgedActionException
as:hbase/aws-scottm-tmh6-1.ap-southeast-1.compute.internal@LAB
(auth:KERBEROS)
cause:org.apache
.hadoop.hdfs.server.namenode.LeaseExpiredException: No lease on
/user/SPN-hbase/.logs/aws-scottm-tmh6-1.ap-southeast-1.compute.internal,8120,1392703714776/aws-scottm-tmh6-1.ap-southeast-1.compute.inter


it seems to be the problem about Kerberos settings.please check the setting

dfs.namenode.keytab.file
dfs.namenode.kerberos.principal

and check something on HBase:

1.Check if the value of "hbase.rootdir" parameter set up in the
hbase-site.xml file is established under the HDFS.
2.using hbase shell . Check if the "create table" command can be executed
correctly

Best regards
