zhong yingqun updated HADOOP-16244:
-----------------------------------
Description:
In hadoop 3.0.0+ , for default RS codec, there is also a native implementation
which leverages Intel ISA-L library to improve the performance of codec. as we
know, ISA-L has set of highly optimized functions include compress/decompress
base on gzip. can ISA-L compatible with hadoop to provide highly performance of
de/compress? however, hadoop comunity seem not support isa-l compression &
decompression up to now. Has some problem in ISA-L compress-support?
Can someone share the experience in this area? thanks a lot!
