stack updated HBASE-7244:
-------------------------
Hadoop Flags: Reviewed
Status: Patch Available (was: Open)
+1 on patch.
Should we add a clean verb to ./bin/hbase under PROCESS MANAGEMENT here:
{code}
durruti:trunk stack$ ./bin/hbase
Usage: hbase <command>
where <command> an option from one of these categories:
DBA TOOLS
shell run the HBase shell
hbck run the hbase 'fsck' tool
hlog write-ahead-log analyzer
hfile store file analyzer
zkcli run the ZooKeeper shell
PROCESS MANAGEMENT
master run an HBase HMaster node
regionserver run an HBase HRegionServer node
zookeeper run a Zookeeper server
rest run an HBase REST server
thrift run the HBase Thrift server
thrift2 run the HBase Thrift2 server
PACKAGE MANAGEMENT
classpath dump hbase CLASSPATH
version print the version
or
CLASSNAME run the class named CLASSNAME
Most commands print help when invoked w/o parameters.
{code}
The clean would call this new script?
> Provide a command or argument to startup, that formats znodes if provided

> Many a times I've had to, and have seen instructions being thrown, to stop
> cluster, clear out ZK and restart.
> While this is only a quick (and painful to master) fix, it is certainly nifty
> to some smaller cluster users but the process is far too long, roughly:
> 1. Stop HBase
> 2. Start zkCli.sh and connect to the right quorum
> 3. Find and ensure the HBase parent znode from the configs (/hbase only by
> default)
> 4. Run an "rmr /hbase" in the zkCli.sh shell, or manually delete each znode
> if on a lower version of ZK.
> 5. Quit zkCli.sh and start HBase again
> Perhaps it may be useful, if the start-hbase.sh itself accepted a formatZK
> parameter. Such that, when you do a {{start-hbase.sh -formatZK}}, it does
> steps 2-4 automatically for you.
> For safety, we could make the formatter code ensure that no HBase instance is
> actually active, and skip the format process if it is. Similar to a HDFS
> NameNode's format, which would disallow if the name directories are locked.
> Would this be a useful addition for administrators? Bigtop too can provide a
> service subcommand that could do this.
