SmartSense based troubleshooting for YARN container apps

avatar
Rising Star

I've been having following questions about SmartSense. Would anyone who has used it, be able to help?

1. We host hbase as YARN app and use slider for the same. I notice that SmartSense has a support for hbase monitoring/ troubleshooting. Just wanted to know if that is extensible to Hbase on Yarn too?

2. Does SmartSense help with piecing together troubleshooting information from so different logs? For example, YARN container app may be down because Yarn node manager went down, which in turn may be down because Yarn RM terminated all apps on that node manager. Piecing this information today requires looking into resource manager/ node manager logs along with Hbase logs.

Another case is that of say, an app going down because ZooKeeper has hit the maxClientCnxns issues and would not allow any more incoming connections from that host.

Those are just representative set of problems. Does SmartSense help there?

3. Does SmartSense also help identify issues such as Kerberos ticket renewal issue, SSL issues, open file handles issues?

Thanks,

Sumit
