>
> A table was created using HCatalog API with out specifying the file format,
> it defaults to:
> {code}
> fileFormat=TextFile, inputformat=org.apache.hadoop.mapred.TextInputFormat,
> outputformat=org.apache.hadoop.hive.ql.io.IgnoreKeyTextOutputFormat
> {code}
> But, when hive fetches the table from the metastore, it strangely replaces
> the output format with
> org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat
> and the comparison between source and target table fails.
> The code in org.apache.hadoop.hive.ql.parse.ImportSemanticAnalyzer#checkTable
> does a string comparison of classes and fails.
> {code}
> // check IF/OF/Serde
> String existingifc = table.getInputFormatClass().getName();
> String importedifc = tableDesc.getInputFormat();
> String existingofc = table.getOutputFormatClass().getName();
> String importedofc = tableDesc.getOutputFormat();
> if ((!existingifc.equals(importedifc))
> || (!existingofc.equals(importedofc))) {
> throw new SemanticException(
> ErrorMsg.INCOMPATIBLE_SCHEMA
> .getMsg(" Table inputformat/outputformats do not match"));
> }
> {code}
> This only affects tables with text and sequence file formats but not rc or
> orc.
