Issue while using Hive View in Ambari console

Contributor

I am facing below issue while using Hive view from Ambari console:

E090 HDFS020 Could not write file /user/admin/hive/jobs/hive-job-3-2016-02-12_12-55/query.hql [HdfsApiException]

Searching through the guides I found out that HDFS user directory set up needs to be done. Following that guide am issuing command hadoop fs -mkdir /user/admin from HDFS user but it throws the below error.

-bash-4.1$ hadoop fs -mkdir /user/admin mkdir: `/user/admin': Input/output error

Need your help on this issue.

Note : Using HDP 2.3.4.0 and it was configured using Amabri and also in that host HDFS client is running.

Re: Issue while using Hive View in Ambari console

Validate HDFS configuration and make sure HDFS service is running.

Input/Output error can be thrown because of multiple reasons (wrong config, NN not available,....)

Could you please check the HDFS Namenode Log and see if any error/exception is shown.

@rajdip chaudhuri Can you please paste /var/log/hadoop/hdfs/<latest_NN>.log and /var/log/ambari-server/ambari-server.log files content. Also please check whether hdfs and ambari service is running.

Re: Issue while using Hive View in Ambari console

@rajdip chaudhuri

yes you need to follow the documentation to do initial setup.

As suggested by Jonas in the above update, please verify and ensure that the HDFS is good by running a

hdfs fsck /user

command as hdfs user. You could check this in the Namenode UI as well.

Also, I hope you are trying to create the folder as 'hdfs' user or with a user who has permission to create /user/admin folder. Are you able to do a

hdfs dfs -ls -R /user

?

Thanks & Rgds

I have same issue on HDP 2.5 & Ambari 2.4.0.1.

I have created all the necessary HDFS directories and grant proper permission, but a simple 'show tables' query just doesn't work. Digging into HDFS logs, I found Ambari Hive View didn't create staging directory under /user/admin/hive/jobs. It should create hive-job-6-2016-12-16_06-15 directory before trying to write the hql file.

$ tail -f hdfs-audit.log | grep '/user/admin'
2016-12-16 06:15:55,156 INFO FSNamesystem.audit: allowed=true ugi=admin (auth:PROXY) via root (auth:SIMPLE) ip=/10.0.0.178  cmd=getfileinfo src=/user/admin/hive/jobs/hive-job-6-2016-12-16_06-15 dst=null  perm=null proto=webhdfs

This error happens after I enabled Ranger plugin for Hive.

I also have another working Ambari Hive View on HDC. It creates the staging directories and hql properly.

Do not know how to fix it..

Also checked NN log, no error occurred.

Re: Issue while using Hive View in Ambari console

Solved this by setting hadoop.proxyuser.root.hosts=*.

For some reason, the HDFS request to create the directory was sent from host where neither Ambari Server nor HS2 is running. Not sure why but change this setting solved the issue.

I had the same problem with a valid Linux/HDFS user as Ambari ID, the solution worked - thanks!

Re: Issue while using Hive View in Ambari console

Thanks your solution of changing hadoop.proxyuser.root.hosts=* also worked for me
