hive - Providing access to unstructured files in Hadoop -


so have collection of files archived in hdfs unique key in file-name. have table of records in hive table same unique key.

how provide access files other users? may need restrict access users.

i thinking of providing reference files in hive table.

i @ sort of web interface searching downloading files.

hive kicks off mapreduce job (or several) every time execute query. latency introduced setting , tearing down mapreduce job(s) exceeds acceptable standards responsivness expected web interface.

i recommend keep metadata files in relational database. have have relational database, postgresql, store hive metadata. sure hope not using default derby that!
