Subject Re: Zookeeper tries to connect to localhost when i have specified another clearly.
Date Wed, 21 Aug 2013 12:29:39 GMT
Sure..
/etc/hosts file:

127.0.0.1 localhost
10.34.187.170 ip-10-34-187-170
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Configuration conf = HBaseConfiguration.create();
conf.set("hbase.zookeeper.quorum", "10.34.187.170");
 conf.set("hbase.zookeeper.property.clientPort","2181");
   conf.set("hbase.master","10.34.187.170");
   Job job = new Job(conf, ViewersTable);

I'm trying to process table data which has 19 million rows..It runs fine
for a while although i don't see the map percent completion change from 0%
.. After a while it says

Task attempt_201304161625_0028_m_000000_0 failed to report status for
600 seconds. Killing!
