[jira] [Updated] (HDFS-15445) ZStandardCodec compression mail fail(generic error) when encounter specific file

Description:
*Problem:*
In our production environment, we put file in hdfs with zstd compressor,
recently, we find that a specific file may leads to zstandard compressor
failures.
And we can reproduce the issue with specific file(attached file: badcase.data)
!image-2020-06-30-11-51-18-026.png|width=1031,height=230!
*Analysis*:
ZStandarCompressor use buffersize( From zstd recommended compress out buffer
size) for both inBufferSize and outBufferSize
!image-2020-06-30-11-35-46-859.png|width=1027,height=387!
but zstd indeed provides two separately recommending inputBufferSize and
outputBufferSize
!image-2020-06-30-11-39-17-861.png!
*Workaround*
One workaround, using recommended in/out buffer size provided by zstd lib can
avoid the problem, but we don't know why.
zstd recommended input buffer size: 1301072 (128 * 1024)
zstd recommended ouput buffer size: 131591

[jira] [Updated] (HDFS-15445) ZStandardCodec compression mail fail(generic error) when encounter specific file

Description:
*Problem:*
In our production environment, we put file in hdfs with zstd compressor,
recently, we find that a specific file may leads to zstandard compressor
failures.
And we can reproduce the issue with specific file(attached file: badcase.data)
!image-2020-06-30-11-51-18-026.png|width=699,height=156!
*Analysis*:
ZStandarCompressor use buffersize( From zstd recommended compress out buffer
size) for both inBufferSize and outBufferSize
!image-2020-06-30-11-35-46-859.png|width=475,height=179!
but zstd indeed provides two separately recommending inputBufferSize and
outputBufferSize
!image-2020-06-30-11-39-17-861.png!
*Workaround*
One workaround, using recommended in/out buffer size provided by zstd lib can
avoid the problem, but we don't know why.
zstd recommended input buffer size: 1301072 (128 * 1024)
zstd recommended ouput buffer size: 131591
