Issue:
The problem occurs on the “CREATE TABLE trucks STORED AS ORC AS SELECT * FROM trucks_stage;”
Error Message:
ERROR : Vertex failed, vertexName=Map 1, vertexId=vertex_1448713152798_0002_2_00, diagnostics=[Task failed, taskId=task_1448713152798_0002_2_00_000000, diagnostics=[TaskAttempt 0 failed, info=[Error: Failure while running task:java.lang.RuntimeException: java.lang.OutOfMemoryError: Java heap space”
might be issue with insufficient Java heap space and try with below script:
CREATE TABLE trucks STORED AS ORC TBLPROPERTIES (“orc.compress.size”=”1024”) AS SELECT * FROM trucks_stage;

Solution:
Our findings:
This issue is happening when we run script from Hue only.
When
running Hive queries through Hue (Beeswax), users are unable to run multiple
queries concurrently. In practice, this doesn't matter if it is separate
browser sessions, separate clients, etc. it seems to be tied to the user.
In
looking at the way Tez works and looking through the code for the patch in Hive
0.14 that supports concurrent queries in general with Tez, it does not support
parallel queries in a particular TezSession, only serial queries. This is also
documented in Tez documentation. It seems the way that Hive creates a session
is based upon the user. Upon further digging, we found a ticket HIVE-9223
that is in open state which describes this issue.

Ambari1.7 throwing an error while re-start any services from ambari
Error message:
Internal Exception: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 80,333,492 milliseconds ago. The last packet sent successfully to the server was 80,333,492 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.
Error Code: 0
Solution:
1. stop ambari-server.
# ambari-server stop
2. Backup the ambari-server.jar:
# mv /usr/lib/ambari-server/ambari-server-1.7.0.169.jar /tmp/
3. copy this ambari-server-1.7.0-9999.jar to /usr/lib/ambari-server/
4. Restart ambari-server
# ambari-server start

Getting Below Error while running hive script
Status: Killed
Job received Kill while in RUNNING state.
Vertex killed, vertexName=Reducer 2, vertexId=vertex_1424221594778_0609_1_02, diagnostics=[Vertex received Kill while in RUNNING state., Vertex killed due to user-initiated job kill. failedTasks:0, Vertex vertex_1424221594778_0609_1_02 [Reducer 2] killed/failed due to:null]
DAG killed due to user-initiated kill. failedVertices:0 killedVertices:1
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.tez.TezTask
Solution:
We observed two problems here
Problem 1: The resultant data set is
very large due to Cartesian join.
Problem 2: NULL / Blank values in JOIN keys
We tuned the script while adding 'where id is not null' condition and it's ran successfully
select
*
from
abc.tmp1 a
left outer join
(select * from app2 where id is not null) b
on a.id=b.id
limit 10;
left outer join
(select * from app2 where id is not null) b
on a.id=b.id
limit 10;
