Hello, Does Hive expose any interesting information or stats over JMX, similarly to Hadoop's JobTracker and NameNode?
I haven't found any in hive 0.8.1 even though f.ex. https://issues.apache.org/jira/browse/HIVE-1818 would indicate that there should be some metrics exposed. (I executed Hive with -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=8008 and connected to it with VisualVM, making use of the MBeans extension to list whatever is available via JMX, which worked well with Hadoop.) Are there some alternative ways to get some monitoring information from Hive? My motivation is that recently we had few hundred corrupted blocks which drove Hive (accessed over Thrift) crazy, namely it was accepting queries but never sent any jobs to the JobTracker and consumed lot of CPU and memory. We weren't able to detect what is going on as there was nothing significant in any log so a better monitoring is certainly needed. Thank you!
