Samarth Jain commented on PHOENIX-1430:
---------------------------------------
[~robertroland] - can you try with phoenix 4.2.1? We have updated the array
data type names in PDataType. For ex - sql type name VARCHAR_ARRAY is now
VARCHAR ARRAY
> Spark queries against tables with VARCHAR ARRAY columns fail

> Key: PHOENIX-1430
> URL: https://issues.apache.org/jira/browse/PHOENIX-1430
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.1
> Reporter: Robert Roland
>
> Running Phoenix 4.1 against HDP 2.2 Preview, I'm unable to execute queries in
> Spark against tables that contain VARCHAR ARRAY columns. Given the error, I
> think it's likely to affect any array column.
> Given the following table schema:
> {noformat}
> CREATE TABLE ARRAY_TEST_TABLE (
> ID BIGINT NOT NULL,
> STRING_ARRAY VARCHAR[]
> CONSTRAINT pk PRIMARY KEY (ID));
> {noformat}
> I am unable to execute a query via Spark, using the PhoenixInputFormat:
> {noformat}
> val phoenixConf = new PhoenixPigConfiguration(new Configuration())
> phoenixConf.setSelectStatement("SELECT ID, STRING_ARRAY FROM
> ARRAY_TEST_TABLE")
> phoenixConf.setSelectColumns("ID,STRING_ARRAY")
> phoenixConf.setSchemaType(SchemaType.QUERY)
> phoenixConf.configure("sandbox.hortonworks.com:2181:/hbase-unsecure",
> "ARRAY_TEST_TABLE", 100)
> val phoenixRDD = sc.newAPIHadoopRDD(phoenixConf.getConfiguration,
> classOf[PhoenixInputFormat],
> classOf[NullWritable],
> classOf[PhoenixRecord])
> val count = phoenixRDD.count()
> {noformat}
> I get the following error:
> {noformat}

> {noformat}
> VARCHAR_ARRAY("VARCHAR_ARRAY", PDataType.ARRAY_TYPE_BASE +
> PDataType.VARCHAR.getSqlType(), PhoenixArray.class, null) { ... }
> {noformat}
> The first parameter there being the sqlTypeName, which is "VARCHAR_ARRAY" but
> it appears to try and look it up as "VARCHAR ARRAY" (space instead of
> underscore)
> I'm not sure if the fix here is to change those values, or if it's deep
> inside MetaDataEndpointImpl where the ProtoBuf returned to the client is
> implemented when a getTable call occurs.
