hbase.master parameter?

What happened to the "hbase.master" parameter?

I dont see it in the docs... was it deprecated?

It appears to still have an effect in 94.7

hi,

I not sure which option you're meant to, in our env., using hbase-0.94.2,
but I can not find the option "hbase.master" in the configs
{code}
 egrep -in --color "hbase\.master" /etc/hbase/conf/*
/etc/hbase/conf/hbase-site.xml:21:    <name>hbase.master.port</name>
/etc/hbase/conf/hbase-site.xml:25:    <name>hbase.master.info.port</name>
/etc/hbase/conf/hbase-site.xml:86:    <name>hbase.master.keytab.file</name>

<name>hbase.master.kerberos.principal</name>
/etc/hbase/conf/hbase-site.xml:94:
<name>hbase.master.kerberos.https.principal</name>
{code}

Also in the git branch
{code}
$ cd hbase

$ git status

Re: hbase.master parameter?

Posted by Jean-Daniel Cryans <jd...@apache.org>.

hbase.master was removed when we added zookeeper, so now a client will do a
lookup in ZK instead of talking to a pre-determined master. So in a
way, hbase.zookeeper.quorum is what replaces hbase.master

FWIW that was done in 0.20.0 which was released in September of 2009, so
hbase.master has been removed 4 years ago.

Thanks for the feedback !

So - are you sure it has no effect?  By "obsolete" - do we mean deprecated?

In this case - which parameters have replaced it and how [specifically] ?

Any help on this issue would be appreciated , because im seeing an effect
when i have the parameter , will check my hbase version and confirm.

That property hasn't been in effect since 0.90 (far as I can
remember). Ever since we switched master discovery to ZK, the property
has been obsolete.
