[jira] [Created] (HBASE-7258) Hbase needs to create baseZNode
recursivly
Liu Shaohui created HBASE-7258:
----------------------------------
Summary: Hbase needs to create baseZNode recursivly
Key: HBASE-7258
URL: https://issues.apache.org/jira/browse/HBASE-7258
Project: HBase
Issue Type: Bug
Components: Zookeeper
Affects Versions: 0.94.2
Reporter: Liu Shaohui
Priority: Critical
In deploy env, multi small hbase clusters may share a same zk cluster. So, for hbase cluster1, its parent znode is /hbase/cluster1. But in hbase version 0.94.1, hbase use ZKUtil.createWithParents(this, baseZNode) to create parent path and it will throw a NoNode exception if znode /hbase donot exist.
We want to change it to ZKUtil.createWithParents(this, baseZNode); to suport create baseZNode recursivly.

Retrying hadoopqa. Patch looks good to me but checking to see if test failures are because of this patch.

Liu Shaohui commented on HBASE-7258:
------------------------------------
For other services likes hdfs,yarn also use the same zk cluster, we want put all our hbase cluster parent znode "cluster#" under the znode "/hbase". I think it looks better in this way.

ramkrishna.s.vasudevan commented on HBASE-7258:
-----------------------------------------------
Ok...so why don't you name the znode as /hbase_cluster1... and for yarn name it as /yarn_cluster1.
Am not trying to find fault here. Just saying.. Thanks for the patch anyway.
Lets see what Ted or Stack has to say on this fix. BTW change does no harm.

ramkrishna.s.vasudevan commented on HBASE-7258:
-----------------------------------------------
Can we make the base znode for diff clusters itself like /cluster1, /cluster2 by setting in the property zookeeper.znode.parent?
May be the node /hbase is not required right? Correct me if am wrong.
