While doing the installation, i keep getting a failure on the step "Creating Oozie database"

java.lang.Exception: DB schema exists
    at org.apache.oozie.tools.OozieDBCLI.validateDBSchema(OozieDBCLI.java:877)
    at org.apache.oozie.tools.OozieDBCLI.createDB(OozieDBCLI.java:184)
    at org.apache.oozie.tools.OozieDBCLI.run(OozieDBCLI.java:127)
    at org.apache.oozie.tools.OozieDBCLI.main(OozieDBCLI.java:78)

How do i fix this? Where do i get the password/username/dbname for the PostgreSQL database to drop the existing schema?

I tried cat /etc/cloudera-scm-server/db*.properties | grep pass

and

/var/lib/cloudera-scm-server-db/data/generated-password.txt

but the passwords don't work!

I am trying to raise the open file descriptor maximum for all users on an ubuntu machine.

This question is somewhat of a follow up to this question.

open file descriptor limits.conf setting isn't read by ulimit even when pam_limits.so is required

except that i've added the required "root" entries in limits.conf

Here are the entries

*               soft    nofile           100000
*               hard    nofile           100000
root            soft    nofile           100000
root            hard    nofile           100000

Lines related to pam_limits.so have been un-commented in all relevant files in /etc/pam.d/ and fs.file-max has been set correctly in /etc/sysctl.conf

However, I still see

abc@machine-2:/etc/pam.d$ ulimit -n
1024

after reboot.

What could be the problem?

My default shell is /bin/sh and i can't use chsh to change my default shell since the my user on the machine is authenticated via some distributed authentication scheme.

I'm trying to install glibc2 version 2.11 that's needed for openoffice 3.4 https://issues.apache.org/ooo/show_bug.cgi?id=119393

but i can't seem to find the dependency with yum. I already have the following dependencies installed.

glibc.i686                                2.5-49.el5_5.7               installed

and

I ran the following to get the version but it shows something different

[root@***** /]# ./lib64/libc.so.6
GNU C Library stable release version 2.5, by Roland McGrath et al.

Can someone please help?

Thanks!
