----------------------------------
Summary: [1.5] Table cache for Parquet broken in 1.5
Key: SPARK-11246
URL: https://issues.apache.org/jira/browse/SPARK-11246
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.5.1
Reporter: David Ross
Since upgrading to 1.5.1, using the {{CACHE TABLE}} works great for all tables
except for parquet tables, likely related to the parquet native reader.
Here are steps for parquet table:
{code}
create table test_parquet stored as parquet as select 1;
explain select * from test_parquet;
{code}
With output:
{code}
== Physical Plan ==
Scan
ParquetRelation[hdfs://192.168.99.9/user/hive/warehouse/test_parquet][_c0#141]
{code}
And then caching:
{code}
cache table test_parquet;
explain select * from test_parquet;
{code}
With output:
{code}
== Physical Plan ==
Scan
ParquetRelation[hdfs://192.168.99.9/user/hive/warehouse/test_parquet][_c0#174]
{code}
Note it isn't cached. I have included spark log output for the {{cache table}}
and {{explain}} statements below.
---
Here's the same for non-parquet table:
{code}
cache table test_no_parquet;
explain select * from test_no_parquet;
{code}
With output:
{code}
== Physical Plan ==
HiveTableScan [_c0#210], (MetastoreRelation default, test_no_parquet, None)
{code}
And then caching:
{code}
cache table test_no_parquet;
explain select * from test_no_parquet;
{code}
With output:
{code}
== Physical Plan ==
InMemoryColumnarTableScan [_c0#229], (InMemoryRelation [_c0#229], true, 10000,
StorageLevel(true, true, false, true, 1), (HiveTableScan [_c0#211],
(MetastoreRelation default, test_no_parquet, None)), Some(test_no_parquet))
{code}
Not that the table seems to be cached.
---
Note that if the flag {{spark.sql.hive.convertMetastoreParquet}} is set to
{{false}}, parquet tables work the same as non-parquet tables with caching.
This is a reasonable workaround for us, but ideally, we would like to benefit
from the native reading.
