Samuel Cozannet (samuel-cozannet) has assigned this bug to you for hdp-hadoop
in Juju Charms Collection:
This bug comes when joining a hdp-pig-4 charm to an existing HDP cluster
made at least of a YARN Master (hdp-hadoop-7) and compute nodes (same
versions)
By default, when creating the cluster, the charms will format a HDFS
partition in /grid/hadoop/hdfs/nn.
When adding the PIG node, it will try to do it again. Except that if it has
already been done, it won't work because it's not enforced or tested.
It then goes into an infinite loop of:
unit-yarn-master-0[28041]: message repeated 3809 times: [ 2015-02-25 09:33:59
INFO unit.yarn-master/0.namenode-relation-joined logger.go:40 Re-format
filesystem in Storage Directory /grid/hadoop/hdfs/nn ? (Y or N) Invalid input: ]
unit-yarn-master-0[28041]: 2015-02-25 09:34:00 INFO
unit.yarn-master/0.namenode-relation-joined logger.go:40 Re-format filesystem
in Storage Directory /grid/hadoop/hdfs/nn ? (Y or N) Invalid input:
The correct behavior should be
* to test if the partition is already formated.
* Pass if yes (we don't know if data has been posted there, don't want to erase
it)
* Create/Format otherwise
