Subject [jira] [Commented] (SPARK-1561) sbt/sbt assembly generates too many local files
Date Tue, 22 Apr 2014 07:31:17 GMT

    [ https://issues.apache.org/jira/browse/SPARK-1561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13976487#comment-13976487
] 

Xiangrui Meng commented on SPARK-1561:
--------------------------------------

Tried adding 

{code}
assemblyOption in assembly ~= { _.copy(cacheUnzip = false) },
assemblyOption in assembly ~= { _.copy(cacheOutput = false) },
{code}

to SparkBuild.scala, but it didn't help reduce the number of files.

>                 Key: SPARK-1561
>                 URL: https://issues.apache.org/jira/browse/SPARK-1561
>             Project: Spark
>          Issue Type: Improvement
>    Affects Versions: 1.0.0
>            Reporter: Xiangrui Meng
>
> Running `find ./ | wc -l` after `sbt/sbt assembly` returned 
> 564365
> This hits the default limit of #INode of an 8GB EXT FS (the default volume size for an
EC2 instance), which means you can do nothing after 'sbt/sbt assembly` on such a partition.
> Most of the small files are under assembly/target/streams and the same folder under examples/.
