[ https://issues.apache.org/jira/browse/HBASE-14777?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14993479#comment-14993479 ]
Bhupendra Kumar Jain commented on HBASE-14777:
----------------------------------------------
The code removes the successful entries from the list of entries. Each removal from the list changes the position of subsequent element of list which results in IndexOutOfBoundsException
{code}
for (Future<Integer> f : futures) {
try {
// wait for all futures, remove successful parts
// (only the remaining parts will be retried)
entryLists.remove(f.get());
} catch (InterruptedException ie) {
iox = new IOException(ie);
}
{code}
To handle this, We can iterate and remove in reverse order.
{code}
int fLen = futures.size();
for (int fIndex = fLen - 1; fIndex >= 0; fIndex--) {
try {
// wait for all futures, remove successful parts
// (only the remaining parts will be retried)
entryLists.remove(futures.get(fIndex).get());
} catch (InterruptedException ie) {
iox = new IOException(ie);
}
{code}
