Ted Yu commented on HBASE-7414:
-------------------------------
Looking at HFileBlock.java:
{code}
static final int MINOR_VERSION_WITH_CHECKSUM = 1;
static final int MINOR_VERSION_NO_CHECKSUM = 0;
{code}
It seems that MINOR_VERSION of 2 doesn't correspond to a particular feature. 2
is just marked as MAX_MINOR_VERSION.
So I guess PBUF_TRAILER_MINOR_VERSION can carry value of 2.
It would be nice if MINOR_VERSION constants can be found in one place so that
it is easier to maintain.
