Hi,
I installed HiveServer2 on ambari 2.6. Whlie accessing hive through terminal or webUI, its not working. The error is comming Error: Could not open client transport with JDBC Url: jdbc:hive2://ip:10000/transportMode=binary:Java.net.ConnectionException (Connection Refused).
SET hive.exec.dynamic.partition = true;
SET hive.exec.dynamic.partition.mode = nonstrict;
SET hive.exec.max.dynamic.partitions = 10000;
SET hive.exec.max.dynamic.partitions.pernode = 1000;
these are the configuration which is available on config file.
Could anybody help regarding this issue would be great.
Thanks.

Looks like a Tuning issue. Here we see that the "Requested Memory" is More than the "Max Memory".
requestedMemory=10096, maxMemory=7936.

Are you able to do Telnet on the HS2 Hostname & Port?
From Hive Client host
# telnet $HS2_HOSTNAME 10000 (OR) # nc -v $HS2_HOSTNAME 10000
.
On the HS2 host can you please check if the port 10000 is listening and bound properly and the IP tables is disabled?
# netstat -tnlpa | grep 10000 # service iptables stop
.
Also please restart HS2 and then see if you find any Errors in the HS2 log?
# ls -l /var/log/hive/hiveserver2.log
.
Also can you please try with the Zookeeper based dynamic URLs? Like following to see if it works?
# beeline -n barney -p bedrock -u "jdbc:hive2://m1.hdp.local:2181,m2.hdp.local:2181,m3.hdp.local:2181/<db>"

Thanks for your quick reply.
I tried telnet $HS 10000 and nc -v $HS 10000, but nothing is coming.
When i run the command "nc -v $HS Host 10000", i got only this Ncat: Version 7.50 ( https://nmap.org/ncat )
Ncat: Connection refused.
Then tried
netstat -tnlpa | grep 10000 but nothing is coming.
When i run i got below error
ls -l /var/log/hive/hiveserver2.log
Caused by: org.apache.hadoop.yarn.exceptions.InvalidResourceRequestException: Invalid resource request, requested memory < 0, or requested memory > max configured, requestedMemory=10096, maxMemory=7936.
Could you pls let me know more about it.
