Venkatesh Seetharam created HIVE-5550: -----------------------------------------
Summary: Import fails for tables created with default text and sequence file formats using HCatalog API Key: HIVE-5550 URL: https://issues.apache.org/jira/browse/HIVE-5550 Project: Hive Issue Type: Bug Affects Versions: 0.11.0 Reporter: Venkatesh Seetharam 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. -- This message was sent by Atlassian JIRA (v6.1#6144)
