If I run with out '--direct' option, I get the communication exception as in
https://issues.cloudera.org/browse/SQOOP-186
I have set 'net-write-timeout' and 'net-read-timeout' values in MySQL to 6000.
My Sqoop command looks like this
sqoop import -D mapred.task.timeout=0 --fields-terminated-by '\t' --escaped-by
'\\' --optionally-enclosed-by '\"' --bindir ./ --connect jdbc:mysql://<remote
ip>/<mysql db> --username tuser --password tuser --table table1
--target-dir=/base/table1 --split-by id -m 8 --direct
