Subject [jira] [Commented] (HADOOP-12979) IOE in S3a: ${hadoop.tmp.dir}/s3a not configured
Date Wed, 30 Mar 2016 14:47:25 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12979?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15218072#comment-15218072
] 

Steve Loughran commented on HADOOP-12979:
-----------------------------------------

The problem is the branch take if there's no s3 buffer dir defined. the else clause is broken;
it's looking for a config option which isn't there.
{code}
    if (conf.get(BUFFER_DIR, null) != null) {
      lDirAlloc = new LocalDirAllocator(BUFFER_DIR);
    } else {
      lDirAlloc = new LocalDirAllocator("${hadoop.tmp.dir}/s3a");   // HERE
    }
{code}

The fix should be to set {{BUFFER_DIR}} to the full path desired, create the {{LocalDirAllocator(BUFFER_DIR)}}
from the (possibly enhanced) config

> Running some spark s3a tests trigger an NPE in Hadoop <=2/7l IOE in 2.8 saying "${hadoop.tmp.dir}/s3a
not configured".
> That's correct: there is no configuration option on the conf called "${hadoop.tmp.dir}/s3a
". There may be one called {{hadoop.tmp.dir}}, however.
> Essentially s3a is sending the wrong config option down, if it can't find {{fs.s3a.buffer.dir}}
