My suggestion is to first do it outside cloudbreak to see if updating mysql jar fixes this issue.

There seems to be some error but you jdbc driver is causing to not show the exact error. Check if can update mysql-connector-java.jar in /usr/hdp/current/hive-server2 with the correct one for your version of mysql server.

If there are no HA components (Namenode HA and 2 hiveserver2 instances), then there is no depending with zookeeper. Check the hiveserver2.log from /var/log/hiveserver2/hiveserver2.log to see if you see any errors. If you have 2 hiveserver2 instances, they will register with zookeeper which may be when they are running into issues.

Try ssh with vagrant ssh <vm>. This setup uses key based authentication and it should never prompt you for password once you use vagrant ssh <vm>

Yes. Once you specific STORED AS ORC, OrcSerde is what is used which ignores those. Your SerDe can decide which of them in create table script can be used.

Once you changed it, try using A_Filtered = FILTER A BY Col1 == '1'; From the error, it shows that right hand side is a number and not a string. Use '' to search for a string and this will work.

1. NN data lost. Is it that the disk with NN directories crashed or have you deleted them? Is this with HA or non-HA. With non-HA, if both data directories of NN have no data, then you will run into data loss issues. You can revive and get to some state from secondary NN data directories but can not guarantee no data loss. If there is no useful data, you can always issue a NN format and start fresh. (You will need to manually update tez and mapreduce apps, you can get the information from manual install documentation) 2. Ambari not starting. Clean up /var/log and start it back. 3. Most likely HDFS services are not up. Filled up disk can kill processes. Once ambari is up, see which one is running and which one is not. Againt if NN data is lost, then NN will not start up.

Is this a reinstall (or upgrade)? If so, please uninstall agent, clear /var/lib/ambari-agent directory and reinstall agent again. Looks to me like old files in cache.
