As I understand it, this is because of the default Hive input format {{CombineHiveInputFormat}} does not handle this correctly. It does not like that there are a mix of data files and some index files, it lumps them altogether when making the combined splits and Mappers fail when they try to process the {{.lzo.index}} files as data. When using the original {{HiveInputFormat}}, it correctly identifies the {{.lzo.index}} files because it considers each file individually. > Allow {{CombineHiveInputFormat}} to short-circuit LZO files and to not combine them. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
