Craig Condit created HIVE-7502: ---------------------------------- Summary: Writes to parquet tables via HCatalog fail with "java.lang.RuntimeException: Should never be used". Key: HIVE-7502 URL: https://issues.apache.org/jira/browse/HIVE-7502 Project: Hive Issue Type: Bug Components: HCatalog Reporter: Craig Condit
Attempting to store data into a Parquet table via HCatalog (using Pig) fails. Based on the code, it appears that org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat.getRecordWriter() is unimplemented. To duplicate: Hive: {noformat} create table parquet_input_test stored as parquet as with x as (select test as value) select * from x; create table parquet_output_test (value int) stored as parquet; {noformat} Pig: {noformat} A = LOAD 'parquet_input_test' USING org.apache.hive.hcatalog.pig.HCatLoader(); STORE A INTO 'parquet_output_test' USING org.apache.hive.hcatalog.pig.HCatStorer(); {noformat} Result: {noformat} java.lang.RuntimeException: Should never be used at org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat.getRecordWriter(MapredParquetOutputFormat.java:76) at org.apache.hive.hcatalog.mapreduce.FileOutputFormatContainer.getRecordWriter(FileOutputFormatContainer.java:103) at org.apache.hive.hcatalog.mapreduce.HCatOutputFormat.getRecordWriter(HCatOutputFormat.java:260) at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.PigOutputFormat.getRecordWriter(PigOutputFormat.java:84) at org.apache.hadoop.mapred.MapTask$NewDirectOutputCollector.<init>(MapTask.java:623) at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:743) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:339) at org.apache.hadoop.mapred.YarnChild$2.run(YarnChild.java:162) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:415) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1491) at org.apache.hadoop.mapred.YarnChild.main(YarnChild.java:157) {noformat} -- This message was sent by Atlassian JIRA (v6.2#6252)
