--------------------------------
Please fix the following compilation errors:
{code}
[ERROR]
/testptch/hbase/hbase-client/src/main/java/org/apache/hadoop/hbase/filter/FilterListWithOR.java:[413,24]
[ArrayHashCode] hashcode method on array does not hash array contents
(see http://errorprone.info/bugpattern/ArrayHashCode)
Did you mean 'return
Objects.hash(this.prevFilterRCList,this.prevCellList,Arrays.hashCode(this.filters.toArray()));'?
[ERROR]
/testptch/hbase/hbase-spark/src/main/java/org/apache/hadoop/hbase/spark/SparkSQLPushDownFilter.java:[307,33]
[ArrayHashCode] hashcode method on array does not hash array contents
(see http://errorprone.info/bugpattern/ArrayHashCode)
Did you mean 'hash=hash+Arrays.hashCode(val);'?
{code}
Please also address findbugs and checkstyle warnings.
