-----------------------------------
Summary: CLONE - Spark build encounters "File name too long" on
some encrypted filesystems
Key: SPARK-21531
URL: https://issues.apache.org/jira/browse/SPARK-21531
Project: Spark
Issue Type: Improvement
Components: Documentation
Reporter: antonkulaga
Assignee: Theodore Vasiloudis
Priority: Minor
Fix For: 1.4.0
This was reported by Luchesar Cekov on github along with a proposed fix. The
fix has some potential downstream issues (it will modify the classnames) so
until we understand better how many users are affected we aren't going to merge
it. However, I'd like to include the issue and workaround here. If you
encounter this issue please comment on the JIRA so we can assess the frequency.
The issue produces this error:
{code}
[error] == Expanded type of tree ==
[error]
[error] ConstantType(value = Constant(Throwable))
[error]
[error] uncaught exception during compilation: java.io.IOException
[error] File name too long
[error] two errors found
{code}
The workaround is in maven under the compile options add:
{code}
+ <arg>-Xmax-classfile-name</arg>
+ <arg>128</arg>
{code}
In SBT add:
{code}
+ scalacOptions in Compile ++= Seq("-Xmax-classfile-name", "128"),
{code}
