I am using the below command to compress the output in *Block Compression*and I have created my table as a *SequenceFile*
*set mapred.output.compress=true;* *set mapred.output.compression.type=BLOCK;* *set mapred.output.compression.codec=org.apache.hadoop.io.compress.LzoCodec; * So after the query is done, when I do *ls*, I see the below file. But when I try to open this file using *hadoop fs -cat, *I see some weird characters in that file, but I can also see my output too. So before viewing this file, I need to decompress it in any format and then I need to do the cat? If yes, then how should I decompress this file? */apps/hdmi/ldata/dt=20120709/attempt_201207311206_11141_r_000000_0*
