J.Andreina created HDFS-3406:
--------------------------------
Summary: Secondary Namenode does not do checkpointing and
Exception message is thrown for ever when "dfs.namenode.checkpoint.dir" and
"dfs.namenode.checkpoint.edits.dir" are configured to an invalid value
Key: HDFS-3406
URL: https://issues.apache.org/jira/browse/HDFS-3406
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: J.Andreina
Priority: Minor
Fix For: 2.0.0, 3.0.0
When "dfs.namenode.checkpoint.dir" and "dfs.namenode.checkpoint.edits.dir" are
configured to an invalid value.
Started NN,DN and SNN
At the SNN side checkpoint does not happens and exception is thrown continously
Expected:
==========
When all the configured values are invalid then Secondary Namenode need not
continue and keeps throwing exception for every checkpointing period
Instead the SNN should get shutdown throwing an exception as Illegal Argument
passed.
SNN side logs:
==============
