-----------------------------------------------------------
I have double checked the code and don't think it's related to this patch
either, as CodecUtil is never used in this class.
By the way, I examined some other bugs when checking all the usages of
CodecUtil. As the configuration of erasure code has been changed, some
configurations should be changed accordingly. The bugs lie in the codes like
the following:
{quote}
if (ErasureCodeNative.isNativeCodeLoaded()) {
conf.set(
CodecUtil.IO_ERASURECODE_CODEC_RS_RAWCODERS_KEY,
NativeRSRawErasureCoderFactory.class.getCanonicalName());
}
{quote}
The configuration is done when native code is loaded, so currently there is no
error displayed. I will correct them immediately.

> This is a follow-on task for HADOOP-13010 as discussed over there. There may
> be some better approach allowing to customize and configure erasure coders
> than the current having raw coder factory, as [~cmccabe] suggested. Will copy
> the relevant comments here to continue the discussion.
