Nitay Joffe commented on HBASE-1329:
------------------------------------
Good idea Lars. Folks please post suggestions for what you would like to have.
Some of my initial thoughts (from above and other chats):
- Add a 'zk' command to the shell. Put all of the ZooKeeper shell commands as
sub commands as this. Specifically here are the current ZooKeeper shell
commands:
{code}commandMap.put("create", "path data acl");
commandMap.put("delete"," path [version]");
commandMap.put("set"," path data [version]");
commandMap.put("get"," path [watch]");
commandMap.put("ls"," path [watch]");
commandMap.put("getAcl"," path");
commandMap.put("setAcl"," path acl");
commandMap.put("stat"," path [watch]");
commandMap.put("sync"," path");
commandMap.put("setquota"," -n|-b val path");
commandMap.put("listquota"," path");
commandMap.put("delquota"," [-n|-b] path");
commandMap.put("history","");
commandMap.put("redo"," cmdno");
commandMap.put("printwatches", " on|off");
commandMap.put("quit","");
commandMap.put("addauth", " scheme auth");
{code}
- Add higher level commands to 'zk', like get/set master addres, get/set root
region server address.
- Add a ZK tree viewer to UI, something like ZOOKEEPER-418.
> Visibility into ZooKeeper

> Key: HBASE-1329
> URL: https://issues.apache.org/jira/browse/HBASE-1329
> Project: Hadoop HBase
> Issue Type: New Feature
> Affects Versions: 0.20.0
> Reporter: Nitay Joffe
> Assignee: Nitay Joffe
> Priority: Blocker
> Fix For: 0.20.0
>
>
> Currently, to the users of HBase ZooKeeper is some mysterious thing that is
> for some reason important but no one knows why. We need to provide more
> visibility into ZooKeeper from HBase.
> This issue is to start a discussion on what sorts of things we can/should
> provide. Some possible ideas to get started:
> - Running a REST server. See ZOOKEEPER-36.
> - FUSE support. See ZOOKEEPER-25.
> - Admin/surgery tools in HBase shell. Answer questions like "in safe mode?"
> - Status and information on HBase's data in ZooKeeper in the web UI.
