Hi @sunile.manjee I am referring to the number of regions. Some of the region servers have 30-40 regions and some have 70-80 regions.

Hi, We are seeing a scenario where HBase regions are not distributed evenly across all HBase region servers, even though balancer_swicth is set to true. This was working fine without any issues until recently. No config changes are made on the HBase cluster or restarts for past 5-6 months. I manually triggered balancer using balancer command from HBase shell, but still no change in region allocation. No errors or warn messages in Master logs. Please let me know what could go wrong and cause this scenario with Hbase. Thanks in advance for the help.

Thanks, @kdoran for the response. Will create JIRA's for new feature requests.

Thanks, @Andrew Lim for the update. Is it a recommended approach to keep db location on a shared mount and start service on multiple servers? I see a risk of data corruption, if multiple services try to write to same file at the same time.

Hi, We are trying out NiFi Registry v 0.1.0.3.1.1.0-35 and is working fine with Single Node setup. But we would like to set it up in cluster mode. Is cluster mode supported for NiFi registry? Currently, Nifi registry is storing data in local database, is it a recommended approach to share this db directory over NFS mount and start nifi registry in HA mode?

Hi, We are looking for NiFi v1.6 to address the below-listed issue. Any idea on when NiFi v1.6 is planned to release as part of HDF? Currently, we are on NiFi v nifi-1.5.0.3.1.1.0-35 and have a requirement to add NiFi cluster behind load balancer. We are hitting below listed bug. https://issues.apache.org/jira/browse/NIFI-4761

Thanks @gnovak currently I am getting app level details similarly as mentioned above using REST API. I am interested to see if there is anything at queue level.

Hi, I am looking for a Resource Manager metric where it emits metrics related to number of containers preempted, amount of preempted MB and Vcores. I am able to get this metric from each application, but looking if resource manager can emit these metrics for each queue. I have searched through all the different metrics in AMS but it doesn't have it. HDPv2.5.0 or Hadoopv2.7.3

Hi @Shyam Shaw Even I am facing the same error message, even though there are read and write permissions on the bucket. Are there any other permissions which needs to be added on Bucket?
