In theory yes.

In practice, the only hbase committers who are members of the hadoop
pmc are those who were anointed way back when hadoop became a TLP
itself.  A few of the hbase committers have been around a good while
now -- years in some cases -- with mountains of patches under their
belt but the notion that these fellas be promoted to the hadoop PMC
has never come up.

I'm now thinking that this state may have been my fault.  I saw a
barrier, perhaps where there was none, between Hadoop PMC and
subprojects.  My thought was that an HBase committer would be a
hard-sell as an Hadoop PMC member unless the HBase committer first
made significant contribution to hadoop in areas other than HBase.
For example, to HDFS.

You have a good point here Dhuba.
