M7 - hbase proxy configuration

Question asked by nirav on Sep 16, 2014
I am trying to setup proxy configuration for mapr datatable so that I can access cluster from my dev machine without any rpc errors (connection refused, timeout etc)

I did following on each cluster node core-site.xml
<property>
<name>hadoop.proxyuser.admin.hosts</name>
<value>*</value>
</property>

<property>
<name>hadoop.proxyuser.admin.groups</name>
<value>*</value>
</property>


I also added linux user on each node with my local(mac) username and id.
`useradd -g admin -u 1698072283 npatel`

rpc error I get is also random (most likely not but I am not able to find the rational behind each)
2014-09-16 14:54:17,9381 ERROR Client fs/client/fileclient/cc/client.cc:3854 Thread: 4496367616 rpc err Operation timed out(60) 28.21 to 10.250.70.110:5660, fid 19558.16.2, upd 0

I have also seen following,
2014-09-16 14:34:36,5963 ERROR Client fs/client/fileclient/cc/client.cc:3854 Thread: 4785074176 rpc err Connection refused(61) 28.21 to 10.250.70.110:5660, fid 19558.16.2, upd 0

Things works if I run my local service (eclipse or tomcat or java) using cluster defined user.
