Subject where clause on Phoenix view built on Hbase table throws error
Date Wed, 05 Oct 2016 14:21:02 GMT
Hi,

I have this Hbase table already populated

 create 'tsco','stock_daily'

and populated using
$HBASE_HOME/bin/hbase org.apache.hadoop.hbase.mapreduce.ImportTsv
-Dimporttsv.separator=',' -Dimporttsv.columns="HBASE_ROW_KEY,
stock_info:stock,stock_info:ticker,stock_daily:Date,stock_daily:open,stock_daily:high,stock_daily:low,stock_daily:close,stock_daily:volume"
tsco hdfs://rhes564:9000/data/stocks/tsco.csv
This works OK. In Hbase I have

hbase(main):176:0> scan 'tsco', LIMIT => 1
ROW                                                    COLUMN+CELL
 TSCO-1-Apr-08
column=stock_daily:Date, timestamp=1475525222488, value=1-Apr-08
 TSCO-1-Apr-08
column=stock_daily:close, timestamp=1475525222488, value=405.25
 TSCO-1-Apr-08
column=stock_daily:high, timestamp=1475525222488, value=406.75
 TSCO-1-Apr-08
column=stock_daily:low, timestamp=1475525222488, value=379.25
 TSCO-1-Apr-08
column=stock_daily:open, timestamp=1475525222488, value=380.00
 TSCO-1-Apr-08
column=stock_daily:stock, timestamp=1475525222488, value=TESCO PLC
 TSCO-1-Apr-08
column=stock_daily:ticker, timestamp=1475525222488, value=TSCO
 TSCO-1-Apr-08
column=stock_daily:volume, timestamp=1475525222488, value=49664486

In Phoenix I have a view "tsco" created on Hbase table as follows:

0: jdbc:phoenix:rhes564:2181> create view "tsco" (PK VARCHAR PRIMARY KEY,
"stock_daily"."Date" VARCHAR, "stock_daily"."close" VARCHAR,
"stock_daily"."high" VARCHAR, "stock_daily"."low" VARCHAR,
"stock_daily"."open" VARCHAR, "stock_daily"."ticker" VARCHAR,
"stock_daily"."stock" VARCHAR, "stock_daily"."volume" VARCHAR)

So all good.

This works

0: jdbc:phoenix:rhes564:2181> select "Date","volume" from "tsco" limit 2;
+-----------+-----------+
|   Date    |  volume   |
+-----------+-----------+
| 1-Apr-08  | 49664486  |
| 1-Apr-09  | 24877341  |
+-----------+-----------+
2 rows selected (0.011 seconds)

However, I don't seem to be able to use where clause!

0: jdbc:phoenix:rhes564:2181> select "Date","volume" from "tsco" where
"Date" = "1-Apr-08";
Error: ERROR 504 (42703): Undefined column. columnName=1-Apr-08
(state=42703,code=504)
org.apache.phoenix.schema.ColumnNotFoundException: ERROR 504 (42703):
Undefined column. columnName=1-Apr-08

Why does it think a predicate "1-Apr-08" is a column.

Any ideas?

Thanks
