> In Hadoop Common, there are several places where the config keys are used by
> the literal strings instead of their names as in configuration key classes.
> The default values have the same issue. For example
> {code:title=in o.a.h.i.f.t.Compression.java}
> conf.setInt("io.compression.codec.lzo.buffersize", 64 * 1024);
> {code}
> should be
> {code}
> conf.setInt(
> CommonConfigurationKeys.IO_COMPRESSION_CODEC_LZO_BUFFERSIZE_KEY,
> CommonConfigurationKeys.IO_COMPRESSION_CODEC_LZO_BUFFERSIZE_DEFAULT);
> {code}
> instead
