Yi Zhou created SPARK-3480:
------------------------------
Summary: Throws out Not a valid command 'yarn-alpha/scalastyle' in
dev/scalastyle for sbt build tool during 'Running Scala style checks'
Key: SPARK-3480
URL: https://issues.apache.org/jira/browse/SPARK-3480
Project: Spark
Issue Type: Bug
Components: Build
Reporter: Yi Zhou
Priority: Minor
Symptom:
Run ./dev/run-tests and dump outputs as following:
SBT_MAVEN_PROFILES_ARGS="-Pyarn -Phadoop-2.3 -Dhadoop.version=2.3.0
-Pkinesis-asl"
[Warn] Java 8 tests will not run because JDK version is < 1.8.
=========================================================================
Running Apache RAT checks
=========================================================================
RAT checks passed.
=========================================================================
Running Scala style checks
=========================================================================
Scalastyle checks failed at following occurrences:
[error] Expected ID character
[error] Not a valid command: yarn-alpha
[error] Expected project ID
[error] Expected configuration
[error] Expected ':' (if selecting a configuration)
[error] Expected key
[error] Not a valid key: yarn-alpha
[error] yarn-alpha/scalastyle
[error] ^
Possible Cause:
I checked the dev/scalastyle, found that there are 2 parameters
'yarn-alpha/scalastyle' and 'yarn/scalastyle' separately,like
echo -e "q\n" | sbt/sbt -Pyarn -Phadoop-0.23 -Dhadoop.version=0.23.9
yarn-alpha/scalastyle \
>> scalastyle.txt
# Check style with YARN built too
echo -e "q\n" | sbt/sbt -Pyarn -Phadoop-2.2 -Dhadoop.version=2.2.0
yarn/scalastyle \
>> scalastyle.txt
>From above error message, sbt seems to complain them due to '/' separator. So
>it can be run through after I manually modified original ones to
>'yarn-alpha:scalastyle' and 'yarn:scalastyle'..
