--------------------------------------
Hi [~Prabhu Joseph]!
Thanks for this patch!
It looks good except one minor thingy:
In YarnConfiguration:
{code:java}
public static final long DEFAULT_LOG_AGGREGATION_DEBUG_FILESIZE = 104857600;
{code}
This is in bytes, right? Dividing this value by 1024 two times gives me 100, so
I guess this is equal to 100MB.
I would include the unit in the name of the constant (bytes).
Also, I would write the value as: 100 * 1024 * 1024;
Maybe you could put this comment to the same line: "100 MB, 104857600 bytes"
Thanks!
