Hive error - not able to run mapreduce based sql queries

from last couple of days not able to execute any sql query which uses mapreduce from hive cli . when checked job status from hue it shows job is in accepted status only and it display error

YARN RM returned a failed response: HTTPConnectionPool(host=‘cxln2.c.thelab-240901.internal’, port=8088): Read timed out. (read timeout=120)

@abhinavsingh - can you please look into it. sql queries are running very slow and its takes around couple hours for sql queries to run

I am looking into it. There might be some problem with YARN
