Rajeshbabu Chintaguntla commented on PHOENIX-2209:
--------------------------------------------------
[~jamestaylor] This is because we are running upsert select query in IndexTool
to prepare index data and load to index table. But the upsert query on local
index generates data without region split key. So all the data is going to only
one region that's the reason why the job is taking more time and also while
querying the table since the is not region start key prefix we are no records
matching the scan boundaries. For local indexes to work we need to make the
changes in upsert compilter to prefix region start key based on data row key. I
have the patch. Will upload patch if you are ok with it.

> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.5.0
> Environment: CDH: 5.4.4
> HBase: 1.0.0
> Phoenix: 4.5.0 (https://github.com/SiftScience/phoenix/tree/4.5-HBase-1.0)
> with hacks for CDH compatibility.

> Original Estimate: 168h

> Using the Asynchronous Index population tool to create local index (of 1
> column) on tables with 10 columns, and 65M, 250M, 340M, and 1.3B rows
> respectively.
> Table Schema as follows (with generic column names):
> {quote}
> CREATE TABLE PH_SOJU_SHORT (
> id INT PRIMARY KEY,
> c2 VARCHAR NULL,
> c3 VARCHAR NULL,
> c4 VARCHAR NULL,
> c5 VARCHAR NULL,
> c6 VARCHAR NULL,
> c7 DOUBLE NULL,
> c8 VARCHAR NULL,
> c9 VARCHAR NULL,
> c10 BIGINT NULL
> )
> {quote}
> Example command used (for 65M row table):
> {quote}
> 0: jdbc:phoenix:localhost> create local index LC_INDEX_SOJU_EVAL_FN on
> PH_SOJU_SHORT(C4) async;
> {quote}
> And MR job started with command:
> {quote}
> $ hbase org.apache.phoenix.mapreduce.index.IndexTool --data-table
> PH_SOJU_SHORT --index-table LC_INDEX_SOJU_EVAL_FN --output-path
> LC_INDEX_SOJU_EVAL_FN_HFILE
> {quote}
> The IndexTool MR jobs finished in 18min, 77min, 77min, and 2hr 34min
> respectively, but all index tables where empty.
> For the table with 65M rows, IndexTool had 12 mappers and reducers. MR
> Counters show Map input and output records = 65M, Reduce Input and output
> records = 65M. PhoenixJobCounters input and output records are all 65M.
