I experience something strange on drill bits, working drillbit on one of the cluster nodes suddenly failed to start, error log mentioned "Failure while initializing values" and "a System Table provider was either not specified or could not be found". I did not change any config and the service just simply failed.
I tried to edit drill-env.sh and set JAVA OPTS to point login.config to opt/mapr/conf/mapr.login.conf (which should already be the default?) and can now login to drill client, but in MCS, drill still appears to be down, I got a feeling that there are two instances of drill setup in the same node and things got messed up somewhere, not sure if zookeeper is involved too.
Another observation is that two log folders show up, one is "log" and the other is "logs"
I don't know if this can be fixed as node1 is not working consistently, is there a way to reinstall drillbits on that node without affecting others?
