Hi,

We are using falcon-0.6.

I am trying to submit Falcon feed schedule as user1 but it throws below error

Permission denied: user=user1, access=WRITE, inode="/apps/falcon/backupCluster/staging/falcon/workflows/feed":falcon:hdfs:drwxr-xr-x

I gave 777 permissions to staging directory but I still see the same error.

I am able to submit the schedule as falcon user but could not as any other user.

Please help me with this

Thanks,

Venkat

This is a known bug in Falcon and was recently fixed in FALCON-1647 (https://issues.apache.org/jira/browse/FALCON-1647). To fixed your issue, please gave 777 permission to the following two directories: /apps/falcon/backupCluster/staging/falcon/workflows/feed and /apps/falcon/backupCluster/staging/falcon/workflows/process. Otherwise, it only allows the first user to submit entities. Thanks.

I think the problems is, though I gave 777 over /apps/falcon/backupCluster/staging, when I tried creating directory under /apps/falcon/backupCluster/staging/falcon/workflows/feed as falcon user, it is created with 755 permissions as below

[falcon@hostname ~]$ hdfs dfs -mkdir /apps/falcon/backupCluster/staging/falcon/workflows/feed/test1

hdfs dfs -ls /apps/falcon/backupCluster/staging/falcon/workflows/feed

drwxr-xr-x - falcon hdfs 0 2015-12-18 09:55 /apps/falcon/backupCluster/staging/falcon/workflows/feed/test1

The directory is not created with 777 permission (umask 022).

Do you think it could be the reason?

Yes. That is correct.
