-------------------------------------

             Summary: Index Rebuilder does not handle INDEX_STATE timestamp check for all index
                 Key: PHOENIX-5048
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5048
             Project: Phoenix
          Issue Type: Improvement
    Affects Versions: 4.14.1
            Reporter: Monani Mihir


After rebuilder is finished for Partial Index Rebuild, It will check if Index state has been updated after Upper bound of the scan we use in partial index Rebuild. If that happens then it will fail Index Rebuild as Index write failure occured while we were rebuilding Index.
{code:java}
MetaDataEndpointImpl.java#updateIndexState
public void updateIndexState(RpcController controller, UpdateIndexStateRequest request,
RpcCallback<MetaDataResponse> done) {
...
if (actualTimestamp > expectedTimestamp) {
builder.setReturnCode(MetaDataProtos.MutationCode.UNALLOWED_TABLE_MUTATION);
builder.setMutationTime(EnvironmentEdgeManager.currentTimeMillis());
done.run(builder.build());
return;
}
...
}{code}
Suppose Data Table has 3 index and above condition becomes true for first index , then we won't even check for remain two Index.


{code:java}
for (PTable indexPTable : indexesToPartiallyRebuild) {
String indexTableFullName = SchemaUtil.getTableName(
indexPTable.getSchemaName().getString(),
indexPTable.getTableName().getString());
if (scanEndTime == latestUpperBoundTimestamp) {
IndexUtil.updateIndexState(conn, indexTableFullName, PIndexState.ACTIVE, 0L, latestUpperBoundTimestamp);
batchExecutedPerTableMap.remove(dataPTable.getName());
LOG.info("Making Index:" + indexPTable.getTableName() + " active after rebuilding");
} else {
// Increment timestamp so that client sees updated disable timestamp
IndexUtil.updateIndexState(conn, indexTableFullName, indexPTable.getIndexState(), scanEndTime * signOfDisableTimeStamp, latestUpperBoundTimestamp);
Long noOfBatches = batchExecutedPerTableMap.get(dataPTable.getName());
if (noOfBatches == null) {
noOfBatches = 0l;
}
batchExecutedPerTableMap.put(dataPTable.getName(), ++noOfBatches);
LOG.info("During Round-robin build: Successfully updated index disabled timestamp for "
+ indexTableFullName + " to " + scanEndTime);
}
}
{code}
