[jira] [Created] (DRILL-2700) Missing/deleted drillbit.log files on
cluster are not reported
Khurram Faraaz created DRILL-2700:
-------------------------------------
Summary: Missing/deleted drillbit.log files on cluster are not reported
Key: DRILL-2700
URL: https://issues.apache.org/jira/browse/DRILL-2700
Project: Apache Drill
Issue Type: Bug
Components: Tools, Build & Test
Affects Versions: 0.9.0
Environment: 4 node cluster on CentOS
Reporter: Khurram Faraaz
Assignee: Steven Phillips
Missing drillbit.log files on cluster, under /opt/mapr/drill/drill-0.9.0/logs/ are not reported as missing. Instead, user is able to issue and execute SQL queries from sqlline prompt. Failing queries are also executed and errors/Exceptions are reported on sqlline prompt, but there is no corresponding drillbit.log file where details must be written to in the case of passing/failing queries.
I have manually deleted the drillbit.log (users can accidentally delete drillbit.log), and continue to execute SQL from sqlline prompt, and in the case of failing SQL there will be no drillbit.log file since it was accidentally deleted, and hence stacktrace and other diagnostic information is lost.
