Dave Latham commented on HBASE-8025:
------------------------------------
[~jmspaggi] I've got no objection to adding the extra parameter, though I'd
prefer to just get zkcli fixed ASAP. If you've got a patch to add it, go for
it - otherwise perhaps create a separate issue?
> zkcli fails when SERVER_GC_OPTS is enabled

> HBASE-7091 added logic to separate GC logging options for some client
> commands versus server commands. It uses a list of known client commands
> ("shell" "hbck" "hlog" "hfile" "zkcli") and uses the server GC logging
> options for all other invocations of bin/hbase. When zkcli is invoked, it in
> turn invokes "hbase org.apache.hadoop.hbase.zookeeper.ZooKeeperMainServerArg"
> to gather the server command line arguments, but because
> org.apache.hadoop.hbase.zookeeper.ZooKeeperMainServerArg is not on the white
> list it enables server GC logging, which causes extra output that causes the
> zkcli invocation to break. HBASE-7153 addressed this but the fix only solved
> the array syntax - not the white list, so the zkcli command still fails.
> There are many other tools you can invoke that are more likely to "client"
> than "server" options. For example, "bin/hbase org.jruby.Main
> region_mover.rb" or "bin/hbase org.apache.hadoop.hbase.mapreduce.CopyTable"
> or "bin/hbase version" or "bin/hbase
> org.apache.hadoop.hbase.mapreduce.Export". The whitelist of server commands
> is shorter and easier to maintain than a whitelist of client commands.
