Region server geting down frequently after system start

I am running hbase on HDP on Amazon machine,

When i reboot my system and start all hbase services, it get started.

But after some time my region server get down.

Latest error that i am getting from its log file is that

org.apache.hadoop.ipc.RemoteException: java.io.IOException: File /apps/hbase/data/usertable/dd5a251551619e0109349a0dce855e1b/recovered.edits/0000000000000001172.temp could only be replicated to 0 nodes, instead of 1
        at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.getAdditionalBlock(FSNamesystem.java:1657)

Now i am not able to start it.

Any suggestion why it is happing.

Thanks in advance.

Make sure you datanodes are up and running. Also, set "dfs.data.dir" to some permanent location, if you haven't done it yet. It defaults to the "/tmp" dir which gets emptied at each restart. Also, make sure that your datanodes are able to talk to the namenode and there is no network related issue and the datanode machines have enough free space left.
