Subject [jira] [Commented] (PHOENIX-3460) Phoenix Spark plugin cannot find table with a Namespace prefix
Date Mon, 04 Sep 2017 14:21:00 GMT


Aritomo Abe commented on PHOENIX-3460:

I have the same problem. But I cannot just use "." to solve this issue. My scheme was created
using the following syntax:

create table if not exists "create table "test_namespace:test_table" (id varchar not null
primary key);

I can work with the table through JDBC, Phoenix console, etc. But not from Spark:

org.apache.phoenix.schema.TableNotFoundException: ERROR 1012 (42M03): Table undefined. tableName=test_namespace:test_table

Spark code is really simple:

import org.apache.hadoop.conf.Configuration
import org.apache.spark.SparkContext
import org.apache.spark.sql.SQLContext
import org.apache.phoenix.spark._

val configuration = new Configuration()
val sqlContext = new SQLContext(sc)

val df = sqlContext.phoenixTableAsDataFrame(
  "\"test_namespace:test_table\"", Array("id"), conf = configuration

>          Issue Type: Bug
>    Affects Versions: 4.8.0
>         Environment: HDP 2.5
>            Reporter: Xindian Long
>              Labels: phoenix, spark
>             Fix For: 4.7.0
> I am testing some code using Phoenix Spark plug in to read a Phoenix table with a namespace
prefix in the table name (the table is created as a phoenix table not a hbase table), but
it returns an TableNotFoundException.
> The table is obviously there because I can query it using plain phoenix sql through Squirrel.
In addition, using spark sql to query it has no problem at all.
> I am running on the HDP 2.5 platform, with phoenix
> The problem does not exist at all when I was running the same code on HDP 2.4 cluster,
with phoenix 4.4.
> Neither does the problem occur when I query a table without a namespace prefix in the
DB table name, on HDP 2.5
> The log is in the attached file: tableNoFound.txt
> My testing code is also attached.
> The weird thing is in the attached code, if I run testSpark alone it gives the above
exception, but if I run the testJdbc first, and followed by testSpark, both of them work.
>  After changing to create table by using
> The phoenix-spark plug in seems working. I also find some weird behavior,
> If I do both the following
> create table ACME.ENDPOINT_STATUS ...
> create table "ACME:ENDPOINT_STATUS" ...
> Both table shows up in phoenix, the first one shows as Schema ACME, and table name ENDPOINT_STATUS,
and the later on shows as scheme none, and table name ACME:ENDPOINT_STATUS.
> However, in HBASE, I only see one table ACME:ENDPOINT_STATUS. In addition, upserts in
the table ACME.ENDPOINT_STATUS show up in the other table, so is the other way around.
