Hello Bharath Vissapragada,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/8426
to look at the new patch set (#2).
Change subject: IMPALA-3887: Use dfs.namenode.replication.min=3
......................................................................
IMPALA-3887: Use dfs.namenode.replication.min=3
Changes the HDFS and HBase configuration of our
mini-cluster to use:
dfs.namenode.replication.min=3
Several of our tests including planner tests
expect HDFS blocks to have exactly three replicas.
With the default HDFS configuration of
dfs.namenode.replication.min=1, HDFS acks writes
as soon as the min replication is satisfied. This
can lead to test failures because HDFS replication
is racing to replicate blocks while our tests
are executing and expecting to see all replicas.
A more detailed description is in the JIRA.
Testing:
- A core/hdfs ran passed
- A core/hdfs run with data loading passed
