sivabalan narayanan updated HUDI-3041:
--------------------------------------
Summary: spark.read fails when drop partitions is used (was: drop
partitions fails with spark.read)
> spark.read fails when drop partitions is used
> ---------------------------------------------
>
> Key: HUDI-3041
> URL: https://issues.apache.org/jira/browse/HUDI-3041
> Project: Apache Hudi
> Issue Type: Bug
> Components: Spark Integration
> Affects Versions: 0.9.0
> Reporter: sivabalan narayanan
> Priority: Major
> Labels: sev:critical, user-support-issues
>
> With 0.9.0, we added support for dropping partition columns after generating
> the partition path for hoodie records. but looks like we have some gaps in
> end to end flow.
>
> hudi serializes partition path fields to table properties and re-uses when in
> need. So, while querying the field may not be part of table schema since hudi
> would have removed the field (along with trimming the schema) completely.
> Stacktrace for Issue (1)
> {code:java}
> scala> val tripsSnapshotDF = spark.read.format("hudi").load(basePath)
> java.lang.IllegalArgumentException: Cannot find column: 'partitionId' in the
> schema[StructField(_hoodie_commit_time,StringType,true),StructField(_hoodie_commit_seqno,StringType,true),StructField(_hoodie_record_key,StringType,true),StructField(_hoodie_partition_path,StringType,true),StructField(_hoodie_file_name,StringType,true),StructField(rowId,StringType,true),StructField(preComb,LongType,true),StructField(name,StringType,true),StructField(versionId,StringType,true),StructField(toBeDeletedStr,StringType,true),StructField(intToLong,IntegerType,true),StructField(longToInt,LongType,true)]
