BELUGA BEHR updated HIVE-16856:
-------------------------------
Description:
MapJoinTableContainerSerDe currently hard-codes the buffer sizes as 4K. If we
remove the explicit buffer size, it will fall back to using the customized
buffer size (or 4K):
{code}
public FSDataInputStream open(Path f) throws IOException {
return open(f, getConf().getInt("io.file.buffer.size", 4096));
}
{code}
