* The library target hdfspp_test_shim_static is
built using the following sources, which
causes duplicate symbols to be defined -
- hdfs_shim.c
- ${LIBHDFSPP_BINDING_C}/hdfs.cc
* ${LIBHDFSPP_BINDING_C}/hdfs.cc is redundant
and removing this fixes the issue.
* This PR passes the necessary CMake args in the
pom.xml needed for building HDFS native client
on Windows.
* These arguments are exposed as maven options
and can be passed from the command-line.
This downgrades jackson from the version switched to in
HADOOP-18033 (2.13.0), to Jackson 2.12.7.
This removes the dependency on javax.ws.rs-api,
so avoiding runtime problems with applications using
jersey-core v1 and/or jsr311-api.
The 2.12.7 release still contains the fix for CVE-2020-36518.

Reduce the ExitUtil synchronized block scopes so System.exit

ABFS rename fails intermittently when the Storage-blob tracking
metadata is in an incomplete state. This surfaces as the error code
404 and an error message of "RenameDestinationParentPathNotFound"
To mitigate this issue, when a request fails with this response.
the ABFS client issues a HEAD call on the source file
and then retries the rename operation again
ABFS filesystem statistics track when this occurs with new counters
rename_recovery
metadata_incomplete_rename_failures
rename_path_attempts
This is very rare occurrence and appears to be triggered under certain
heavy load conditions, just as with HADOOP-18163.

This feature adds methods for ranged vectored read operations
in PositionedReadable.
All stream which implement that interface support the new API.
The default implementation reads each range in the vector
sequentially.
However, specific implementations may provide higher performance
versions. This is done in two places
* Local FileSystem/Checksum FileSystem
* The S3A client.
The S3A client first coalesces adjacent and "nearby" ranges
together, then fetches each range in separate HTTP GET requests,
executed in parallel. As such it delivers significant speedups
to applications reading separate blocks of data from the same
file, columnar data format libraries in particular.
This is the merge commit of the feature branch; the work is in
HADOOP-11867. Add a high-performance vectored read API.
HADOOP-18104. S3A: Add configs to configure minSeekForVectorReads and maxReadSizeForVectorReads.

part of HADOOP-18103.
Handling memory fragmentation in S3A vectored IO implementation by
allocating smaller user range requested size buffers and directly
filling them from the remote S3 stream and skipping undesired
data in between ranges.
This patch also adds aborting active vectored reads when stream is
closed or unbuffer() is called.
