So the root of the problem (as you've found) is that our ALTER INDEX call does
not cause the data table to be sent over again next time. I think the easiest
way to solve this is to do a Put on the data table by adding it to the
tableMetaData before you call region.mutateRowsWithLocks(tableMetadata,
Collections.<byte[]> emptySet()), here in updateIndexState():
{code}

Maybe you can just do a put on the empty key value (as you know the value is an
empty byte array without having to look it up)? Might need to tweak the logic
that calculates the timeStamp in getTable(). Just add the following to the else
block as well, like this, so that if the empty key value has the biggest ts,
it'll be used too:
{code}
private PTable getTable(RegionScanner scanner, long clientTimeStamp, long
tableTimeStamp) {
...
while (i < results.size() && j < TABLE_KV_COLUMNS.size()) {
Cell kv = results.get(i);
timeStamp = Math.max(timeStamp, kv.getTimestamp()); // Find max
timestamp of table header row
Cell searchKv = TABLE_KV_COLUMNS.get(j);
int cmp =
Bytes.compareTo(kv.getQualifierArray(),
kv.getQualifierOffset(),
kv.getQualifierLength(), searchKv.getQualifierArray(),
searchKv.getQualifierOffset(),
searchKv.getQualifierLength());
if (cmp == 0) {
tableKeyValues[j++] = kv;
i++;
} else if (cmp > 0) {
tableKeyValues[j++] = null;
} else {
i++; // shouldn't happen - means unexpected KV in system table
header row
}
}
{code}
