I am using the below regex(tab seperated) to parse the data(also tab seperated) which is given.
Hive table creation syntax:
create table akmlogreg(logdate string, time string, clientip string, method string, uri string, status string, bytes string, TimeTakenMS string, referer string, useragent string, cs_Cookie string) ROW FORMAT SERDE
'org.apache.hadoop.hive.contrib.serde2.RegexSerDe'
WITH SERDEPROPERTIES (
"input.regex" ="([0-9-]+) ([^\t]*) ([^\t]*) ([^\t]*) ([^\t]*) ([^\t]*) ([^\t]*) ([^\t]*) (\".*\"|[^ ]*) (\".*\"|[^ ]*) ([^\r\n]+)",
"output.format.string"="%1$s %2$s %3$s %4$s %5$s %6$s %7$s %8$s %9$s %10$s %11$s");
through this regex i want any comments (lines starting with #) should be removed and select only one row at a time. But this syntax gives error when i try to create the table in hive. My logic behind tab separated regex is that my log data is also tab separated. Can anyone give me a better suggesion or solution by which i can parse this kind of data which is tab seperated using regex?

Try this:
^([0-9-]+)\t([^\t]*)\t([^\t]*)\t([^\t]*)\t([^\t]*)\t([^\t]*)\t([^\t]*)\t([^\t]*)\t(\".*?\"|[^ ]*)\t(\".*?\"|[^ ]*)\t([^\r\n]+)$
