Exclude bound local addresses, including the use of a wildcard address in the bound host configurations.
* Allow sync attempts with unresolved addresses
* Update the comments.
* Remove unused import
Signed-off-by: stack <stack@apache.org>
Avoid reconnecting to the old address after detecting that the address has been updated.
* Fix Checkstyle line length violation
* Keep ConnectionId as Immutable for map key
The ConnectionId is used as a key in the connections map, and updating the remoteId caused problems with the cleanup of connections when the removeMethod was used.
Instead of updating the address within the remoteId, use the removeMethod to cleanup references to the current identifier and then replace it with a new identifier using the updated address.
* Use final to protect immutable ConnectionId
Mark non-test fields as private and final, and add a missing accessor.
* Use a stable hashCode to allow safe IP addr changes
* Add test that updated address is used
Once the address has been updated, it should be used in future calls. Check to ensure that a second request succeeds and that it uses the existing updated address instead of having to re-resolve.

This is the the preview release of the HADOOP-18028 S3A performance input stream.
It is still stabilizing, but ready to test.

HADOOP-18254. Disable S3A prefetching by default. (#4469)
Contributed by Ahmar Suhail
HADOOP-18190. Collect IOStatistics during S3A prefetching (#4458)
This adds iOStatisticsConnection to the S3PrefetchingInputStream class, with
new statistic names in StreamStatistics.
This stream is not (yet) IOStatisticsContext aware.

JobID.toString() and TaskID.toString() to only be called
when the IDs are not null.
This doesn't surface in MapReduce, but Spark SQL can trigger
in job abort, where it may invok abortJob() with an
incomplete TaskContext.
This patch MUST be applied to branches containing
HADOOP-17833. "Improve Magic Committer Performance."

When the MiniDFSClsuter detects that an exception caused an exit, it should include that exception as the cause for the AssertionError that it throws. The current AssertError simply reports the message "Test resulted in an unexpected exit" and provides a stack trace to the location of the check for an exit exception. This patch adds the original exception as the cause of the AssertError.
The name of the option to enable/disable thread level statistics is
"fs.iostatistics.thread.level.enabled";
There is also an enabled() probe in IOStatisticsContext which can
be used to see if the thread level statistics is active.
