Adds new environment variable IMPALA_JDK_VERSION which can be 'system',
'8', or '11'. The default is 'system', which uses the same logic as
before. If set to 8 or 11, it will ignore the system java and search for
java of that specific version (based on specific directories for Ubuntu
and Redhat). This is used by bin/bootstrap_system.sh to determine
whether to install java 8 or java 11 (other versions can come later). If
IMPALA_JDK_VERSION=11, then bin/start-impala-cluster.py adds the opens
needed to deal with the ehcache issue.
This no longer puts JAVA_HOME in bin/impala-config-local.sh as part of
bootstrap_system.sh. Instead, it provides a new environment variable
IMPALA_JAVA_HOME_OVERRIDE, which will be preferred over
IMPALA_JDK_VERSION.
This also updates the versions of Maven plugins related to the build.
Source and target releases are still set to Java 8 compatibility.
Adds a verifier to the end of run-all-tests that
InaccessibleObjectException is not present in impalad logs. Tested with
JDBC_TEST=false EE_TEST=false FE_TEST=false BE_TEST=false \
CLUSTER_TEST_FILES=custom_cluster/test_local_catalog.py \
run-all-tests.sh
Testing: ran test suite with Java 11
This reverts the revert commit 1b6011c, restoring these changes minus
code to update IMPALA_JDK_VERSION based on $JAVA -version as that could
break subsequent sourcing of impala-config.sh.

This is a tool to convert a nested dataset to an unnested dataset. The source and/or
destination can be the local file system or HDFS.
Structs get converted to a column (with a long name). Arrays and Maps get converted to
a table which can be joined with the parent table on id column.
$ mvn exec:java \
-Dexec.mainClass=org.apache.impala.infra.tableflattener.Main \
-Dexec.arguments="file:///tmp/in.parquet,file:///tmp/out,-sfile:///tmp/in.avsc"
$ mvn exec:java \
-Dexec.mainClass=org.apache.impala.infra.tableflattener.Main \
-Dexec.arguments="hdfs://localhost:20500/nested.avro,file://$PWD/unnested"
There are various options to specify the type of input file but the output is always
parquet/snappy.
For additional help, use the following command:
$ mvn exec:java \
-Dexec.mainClass=org.apache.impala.infra.tableflattener.Main -Dexec.arguments="--help"
This is used by testdata/bin/generate-load-nested.sh.
