----------------------------------
Summary: Using more meaningful keys in EC schema
Key: HADOOP-12065
URL: https://issues.apache.org/jira/browse/HADOOP-12065
Project: Hadoop Common
Issue Type: Sub-task
Reporter: Kai Zheng
Assignee: Kai Zheng
Commented by [~szetszwo] in HADOOP-12029:
bq. We should also change "k" and "m" in the following to something like
"numDataUnits" and "numParityUnits".
{code}
public static final String NUM_DATA_UNITS_KEY = "k";
public static final String NUM_PARITY_UNITS_KEY = "m";
{code}
This sounds good to me, as in fact in many erasure coding related papers,
discussions, and implementations, though {{k}} and {{m}} are broadly used, the
meanings are not consistent. For example, {{m}} can also mean {{numDataUnits +
numParityUnits}}, all the rows in the coding matrix. The suggested names are
more clear and explicit.
