namenode service failed to start -- java heap dump

We are trying to bring up HDP on 3 nodes. After installation, we found that the name node is failing to start. Following is the log:

Re: namenode service failed to start -- java heap dump

@K D

It does not look like a Heap issue, Your NameNode is not starting because it looks like you do not have correct permission "hdfs:hadoop" in the mentioned directory:

2017-09-28 01:02:32,556 ERROR namenode.NameNode (NameNode.java:main(1774)) - Failed to start namenode.
    java.io.FileNotFoundException: /mach/hadoop/hdfs/namenode/current/VERSION (Permission denied)

.

Please change the permission as following and then restart NameNode again:

# chown -R "hdfs:hadoop" /mach/hadoop/hdfs/namenode

Re: namenode service failed to start -- java heap dump

@Jey SenSharma:

Thanks for your help. After setting permission as suggested by you, now we are waiting for namenode to come up.

'/usr/hdp/current/hadoop-hdfs-namenode/bin/hdfs dfsadmin -fs hdfs://mach.openstacklocal:8020 -safemode get | grep 'Safe mode is OFF'' returned 1.<br>

Learned that this wait is natural in namenode start-up as in: Name node start up operations

Thanks,

KD

Re: namenode service failed to start -- java heap dump

It's a permission issue. Please check the the file privilege. ( /mach/hadoop/hdfs/namenode/current/VERSION)

2017-09-2801:02:32,556 ERROR namenode.NameNode(NameNode.java:main(1774))-Failed to start namenode.
