@prabhat10,
The logs you pasted in came in one line; I was able to add some hard returns in to make it easier to read. We can see that it appears that HBase Thrift calls are succeeding but slowly:

This indicates that the HBase Thrift Server is receiving the requests from Hue and is returning a result.
I noted in your log that it appears Hive requests are slow to return as well:

This may indicate that one or more of your services is not able to perform as quickly as we may expect. I would recommend looking more closely at the HBase Thrift Server itself to review its logs and see if there are any clues regarding what is taking longer than one would expect. From what I see in the Hue log you provided, there is no indication that the HBase queries are failing at the Hue --> HBase Thrift connection side.
