Ding Yuan updated HBASE-10813:
------------------------------
Attachment: HBase-10813-trunk.patch
> Possible over-catch of exceptions
> ---------------------------------
>
> Key: HBASE-10813
> URL: https://issues.apache.org/jira/browse/HBASE-10813
> Project: HBase
> Issue Type: Improvement
> Components: regionserver, util
> Affects Versions: 0.96.1
> Reporter: Ding Yuan
> Attachments: HBase-10813-trunk.patch
>
>
> There are a few cases found by a tool that are possibly over-catch of
> exceptions, especially those that will abort the server. Over-catching these
> exceptions may unexpectedly abort the server, and may cause problems in the
> future when code in the try-block evolves. I am attaching a patch against
> trunk that constrains the catch blocks to the exact exceptions that were
> thrown.
> My tool actually found one more case in 0.96.1, but I found it has already
> been fixed in trunk:
> {noformat}
> Line: 1175, File: "org/apache/hadoop/hbase/master/SplitLogManager.java"
> 1173: try {
> 1174: Thread.sleep(20);
> 1175:- } catch (Exception ignoreE) {
> 1175:+ } catch (InterruptedException e) {
> 1176: // ignore
> 1177: }
> {noformat}
> Any feedbacks are much appreciated!
