Re: zstd codec
Yes, it should be part of your Hadoop distribution. Since the zstd will
call native implementations to speed up the decompression these libraries
need to be there at compile-time to wire everything correctly.
You can check if they are:
$ hadoop checknative -a
14/12/06 01:30:45 WARN bzip2.Bzip2Factory: Failed to
load/initialize native-bzip2 library system-native, will use pure-Java
version
14/12/06 01:30:45 INFO zlib.ZlibFactory: Successfully loaded &
initialized native-zlib library
Native library checking:
hadoop: true /home/ozawa/hadoop/lib/native/libhadoop.so.1.0.0
zlib: true /lib/x86_64-linux-gnu/libz.so.1
snappy: true /usr/lib/libsnappy.so.1
zstd: true /usr/lib/libzstd.so.1
lz4: true revision:99
bzip2: false
Hope this helps.
Cheers, Fokko
