Description

Presently the job name length is capped at 20, But in many cases(One being Hive). The length gets crossed in too many cases and post that it doesn't fetch much value.

 

Propose to increase the length limit from 20->35 here:

writer.printf(dataPattern, job.getJobID().toString(),
    job.getJobName().substring(0, jobNameLength > 20 ? 20 : jobNameLength),
