Subject Re: Rebalance HDFS - Issue
Date Tue, 03 Nov 2015 03:20:48 GMT
Sorry, my bad. I meant to ask what "get" returns?


/var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin@DEV get mstd01.corp.com<http://mstd01.corp.com/>
BDP2_DEV hdfs-site​


Similarly, what does http://mstd01.corp.com:8080/api/v1/clusters/BDP2_DEV/configurations?type=hdfs-site
return?


Also, I think the delete may have some issue - what version of Ambari are you using/?


This is what I see ...


[root@c6402 vagrant]# /var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin
delete localhost c1  hdfs-site dfs.namenode.rpc-address

           ...

I have restart HDFS after executing this. The output of this command:

[root@mstd01~]# /var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin@DEV
delete mstd01.corp.com<http://mstd01.corp.com> BDP2_DEV hdfs-site “dfs.namenode.rpc-address”
USERID=admin
PASSWORD=admin@DEV
########## Performing 'delete' “dfs.namenode.rpc-address”: on (Site:hdfs-site, Tag:version1446466158434)
########## PUTting json into: doSet_version1446466579436571830.json
########## NEW Site:hdfs-site, Tag:version1446466158434

But still that property is exists in Ambari->HDFS->Config.

What do you get when you use this -


/var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin@DEV delete mstd01.corp.com<http://mstd01.corp.com>
BDP2_DEV hdfs-site​


Did you restart after the delete?

Hi Sumit,

Thank you for your assistance.

I have tried to remove "dfs.namenode.rpc-address" property using below command, it went successfully,
but still that property exists.

[root@mstd01~]# sudo /var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin@DEV
delete mstd01.corp.com<http://mstd01.corp.com> BDP2_DEV hdfs-site “dfs.namenode.rpc-address”
[sudo] password for root:
USERID=admin
PASSWORD=admin@DEV
########## Performing 'delete' “dfs.namenode.rpc-address”: on (Site:hdfs-site, Tag:version1446466158434)
########## PUTting json into: doSet_version1446466579436571830.json
########## NEW Site:hdfs-site, Tag:version1446466158434

Please help me to fix this issue.

Thanks,
Shaik

​Likely "dfs.namenode.rpc-address" in hdfs-site has a wrong value. If it is, you can delete
it - see https://cwiki.apache.org/confluence/display/AMBARI/Modify+configurations (section
Edit  Configurations with configs.sh)

Subject: Rebalance HDFS - Issue

Hi,

I am trying to run HDFS balancer from Ambari 2.1.2 with HDP 2.3.2, it's failing with following
exception.


15/11/02 03:07:00 INFO block.BlockTokenSecretManager: Setting block keys
15/11/02 03:07:00 INFO balancer.KeyManager: Update block keys every 2hrs, 30mins, 0sec
java.io.IOException: Another Balancer is running..  Exiting ...
Nov 2, 2015 3:07:00 AM   Balancing took 1.935 seconds

I have verified respective Hadoop NN, there is no balancer on NameNode.

Could you please help use to fix this issue.


Thanks,

Shaik M
