In Spark 1.2 I used to be able to do this: scala> org.apache.spark.sql.hive.HiveMetastoreTypes.toDataType("struct<int:bigint>") res30: org.apache.spark.sql.catalyst.types.DataType = StructType(List(StructField(int,LongType,true)))
That is, the name of a column can be a keyword like "int". This is no longer the case in 1.3: data-pipeline-shell> HiveTypeHelper.toDataType("struct<int:bigint>") org.apache.spark.sql.sources.DDLException: Unsupported dataType: [1.8] failure: ``>'' expected but `int' found struct<int:bigint> ^ at org.apache.spark.sql.sources.DDLParser.parseType(ddl.scala:52) at org.apache.spark.sql.hive.HiveMetastoreTypes$.toDataType(HiveMetastoreCatalog.scala:785) at org.apache.spark.sql.hive.HiveTypeHelper$.toDataType(HiveTypeHelper.scala:9) Note HiveTypeHelper is simply an object I load in to expose HiveMetastoreTypes since it was made private. See https://gist.github.com/nitay/460b41ed5fd7608507f5 <https://app.relateiq.com/r?c=chrome_gmail&url=https%3A%2F%2Fgist.github.com%2Fnitay%2F460b41ed5fd7608507f5&t=AFwhZf262cJFT8YSR54ZotvY2aTmpm_zHTSKNSd4jeT-a6b8q-yMXQ-BqEX9-Ym54J1bkDFiFOXyRKsNxXoDGIh7bhqbBVKsGGq6YTJIfLZxs375XXPdS13KHsE_3Lffk4UIFkRFZ_7c> This is actually a pretty big problem for us as we have a bunch of legacy tables with column names like "timestamp". They work fine in 1.2, but now everything throws in 1.3. Any thoughts? Thanks, - Nitay Founder & CTO
