> We get an ArrayIndexOutOfBoundsException during the major compaction check as follows

> This happens due to the following lines in org.apache.hadoop.hbase.regionserver.compactions.DateTieredCompactionPolicy.selectMajorCompaction
> {noformat}
> int lowerWindowIndex = Collections.binarySearch(boundaries,
>         minTimestamp == null ? Long.MAX_VALUE : file.getMinimumTimestamp());
>       int upperWindowIndex = Collections.binarySearch(boundaries,
>         file.getMaximumTimestamp() == null ? Long.MAX_VALUE : file.getMaximumTimestamp());
> {noformat}
> These return negative values if the element is not found and in the case the values are
equal we get the exception.
