try to read content of stored file

y_823910@... 2010-09-09, 01:07

Hi there,

I am very curious about the content of Hbase store file.
Try to read it by HDFS java API, but it's hard to understand these data due
to alot of invisible codes.
Any suggestion?

Try this tool:

$ ./bin/hbase org.apache.hadoop.hbase.io.hfile.HFile

Doing the above dumps out usage. You can pass a filename -- specify
it fully with its hdfs schema as in hdfs://a:9000/hbase/.META./12/34
-- or pass the name of a region and it'll dump all therein.

Let us know if its not working for you.

Try this tool:

$ ./bin/hbase org.apache.hadoop.hbase.io.hfile.HFile

Doing the above dumps out usage. You can pass a filename -- specify
it fully with its hdfs schema as in hdfs://a:9000/hbase/.META./12/34
-- or pass the name of a region and it'll dump all therein.

Re: try to read content of stored file

Looks like you need to pass -f so:

$ ./bin/hbase org.apache.hadoop.hbase.io.hfile.HFile -v -f
hdfs://x:9000/hbase/TestTable/efeb1bab2d99b205ec8837fc40d7010a/info/5319664235715793176

... but then you'll probably get this:

java.lang.IllegalArgumentException: Wrong FS.....

I'll fix this in TRUNK

Meantime, copy the file down from hdfs and pass it to the script (w/
the -f and -v flags).

I've copy the file from hdfs to my local machine.
but sorry! I don't know how to pass it to the script w/ the -f and -v

Could you give me a example.

Looks like you need to pass -f so:

hdfs://x:9000/hbase/TestTable/efeb1bab2d99b205ec8837fc40d7010a/info/5319664235715793176

Re: try to read content of stored file

just a minor point:

./bin/hbase org.apache.hadoop.hbase.io.hfile.HFile -v -f <file name>
where filename should be the configured fs (local/hdfs). "-f" option is
necessary to read a given file. In case one gives wrong dfs, it will give
error.

hbase org.apache.hadoop.hbase.io.hfile.HFile -vf

Re: try to read content of stored file

I got a hbase file from HDFS to /Cloud_Computing/tmp/ttt.txt
I am sure the ttt.txt is in the /Cloud_Computing/tmp, I don't know why it
still showed file doesn't exist

./hbase org.apache.hadoop.hbase.io.hfile.HFile -v -f /Cloud_Computing/tmp
Scanning -> /Cloud_Computing/tmp
ERROR, file doesnt exist: /Cloud_Computing/tmp

./hbase org.apache.hadoop.hbase.io.hfile.HFile -v -f
/Cloud_Computing/tmp/ttt.txt
Scanning -> /Cloud_Computing/tmp/ttt.txt
ERROR, file doesnt exist: /Cloud_Computing/tmp/ttt.txt

Just pass the path as an argument. For example if the file i sin
current directory named 5319664235715793176:

$ ./bin/hbase org.apache.hadoop.hbase.io.hfile.HFile -v -f
./5319664235715793176
