HBase replication
Hi guys,
I need help with HBase replication troubleshooting.
On active master I get the following:
Traceback (most recent call last):
File "/var/lib/ambari-agent/cache/host_scripts/alert_hbase_replication.py", line 123, in execute
raise Exception('The following region servers breached log/replication thresholds:\n'+'\n'.join(breached))
Exception: The following region servers breached log/replication thresholds:

Hi Raymond, tanks for quick pick-up on the question. Yes, the slaves are up and as of slow network - let me check on the monitoring, let's see if there are any bottlenecks. Will update after checks )

Hi Andrey,
My knowledge in HBase is basic hence won't be able to suggest much in this domain. Is the network I/O slow between your clusters? And also are your slave (replication target) clusters down?

Hi Andrey,
Just to follow up on this, have you resolved your issue?
