> Call recoverLease on DFSOutputStream close exception

> Key: HDFS-14694
> URL: https://issues.apache.org/jira/browse/HDFS-14694
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs-client
> Reporter: Chen Zhang
> Assignee: Lisheng Sun
> Priority: Major
> Attachments: HDFS-14694.001.patch, HDFS-14694.002.patch,

>
> HDFS uses file-lease to manage opened files, when a file is not closed
> normally, NN will recover lease automatically after hard limit exceeded. But
> for a long running service(e.g. HBase), the hdfs-client will never die and NN
> don't have any chances to recover the file.
> Usually client program needs to handle exceptions by themself to avoid this
> condition(e.g. HBase automatically call recover lease for files that not
> closed normally), but in our experience, most services (in our company) don't
> process this condition properly, which will cause lots of files in abnormal
> status or even data loss.
> This Jira propose to add a feature that call recoverLease operation
> automatically when DFSOutputSteam close encounters exception. It should be
> disabled by default, but when somebody builds a long-running service based on
> HDFS, they can enable this option.
> We've add this feature to our internal Hadoop distribution for more than 3
> years, it's quite useful according our experience.
