Hi,
I tried to compile HBaseFsck.java for 0.20.5 but got:

compile-core:
    [javac] Compiling 338 source files to

Advice is welcome.

I produced patched version of HBaseFsck.java which is attached.

When I ran it, I got:

Make sure conf directory is in your classpath.  If it is, it might the
case that you need something like the below:

# Set hadoop filesystem configuration using the hbase.rootdir.
# Otherwise, we'll always use localhost though the hbase.rootdir
# might be pointing at hdfs location.
c.set("fs.default.name", c.get(HConstants::HBASE_DIR))
fs = FileSystem.get(c)

The above is copied from the jruby scripts in the bin dir......

...though looking at the HBaseFsck it does this.

So it must be a case of your not setting up the classpath properly?

You've set the target hdfs in your hbase-site.xml and then you've
launched the script as per:

./bin/hbase org.apache.hadoop.hbase.client.HBaseFsck

(The above will ensure your classpath is set properly).

I assume the conf directory is that of HBase.

I use this command previously:
bin/hbase hbck

I tried this today:
bin/hbase org.apache.hadoop.hbase.client.HBaseFsck

Result is the same.

I do see conf in the classpath:

HBaseFsck does this:

    conf.set("fs.defaultFS", conf.get("hbase.rootdir"));

Add this line:

    conf.set("fs.default.name", conf.get("hbase.rootdir"));

See if that fixes it (The former is new way of spec'ing defaultFS
while latter is oldstyle).

That fixes the issue.

HBaseFsck found missing tables after scanning hdfs (possibly from previous
release of HBase - I installed 0.20.5 recently):
ERROR: Path hdfs://
sjc9-flash-grid04.ciq.com:9000/hbase/TRIAL-ERRORS-1277252980233-0 does not
have a corresponding entry in META.

Is there a way to add those tables back ?

Thanks
