+1 from me. I checked sigs/licenses, and built/tested from source on
Java 8 + Ubuntu 18.04 with " -Pyarn -Phive -Phive-thriftserver
-Phadoop-2.7 -Pmesos -Pkubernetes -Psparkr -Pkinesis-asl". I do get
test failures, but, these are some I have always seen on Ubuntu, and I
do not know why they happen. They don't seem to affect others, but,
let me know if anyone else sees these?


Always happens for me:

- HDFSMetadataLog: metadata directory collision *** FAILED ***
  The await method on Waiter timed out. (HDFSMetadataLogSuite.scala:178)

This one has been flaky at times due to external dependencies:

org.apache.spark.sql.hive.HiveExternalCatalogVersionsSuite *** ABORTED ***
  Exception encountered when invoking run on a nested suite -
spark-submit returned with exit code 1.
  Command line: './bin/spark-submit' '--name' 'prepare testing tables'
'--master' 'local[2]' '--conf' 'spark.ui.enabled=false' '--conf'
'spark.master.rest.enabled=false' '--conf'
'spark.sql.warehouse.dir=/data/spark-2.4.5/sql/hive/target/tmp/warehouse-c2f762fd-688e-42b7-a822-06823a6bbd98'
'--conf' 'spark.sql.test.version.index=0' '--driver-java-options'
'-Dderby.system.home=/data/spark-2.4.5/sql/hive/target/tmp/warehouse-c2f762fd-688e-42b7-a822-06823a6bbd98'
'/data/spark-2.4.5/sql/hive/target/tmp/test7297526474581770293.py'

Kafka doesn't build with this weird error. I tried a clean build. I
think we've seen this before.

[error] This symbol is required by 'method
org.apache.spark.metrics.MetricsSystem.getServletHandlers'.
[error] Make sure that term eclipse is in your classpath and check for
conflicting dependencies with `-Ylog-classpath`.
[error] A full rebuild may help if 'MetricsSystem.class' was compiled
against an incompatible version of org.
