I have problems trying to install a new CDH5 cluster with cloudera. Using parcels everything goes fine except when oozie's sharedlib is installed. It fails uploading due to end of time-out.

Then I tried using packages but is worse. The cluster install fails downloading packages: "Operation too slow... trying another mirror... no more mirrors to try... giving up"

Downloading Packages: http://archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/5/RPMS/noarch/bigtop-utils-0.7.0%2Bcdh5.2.0%2B0-1.cdh5.2.0.p0.40.el6.noarch.rpm: [Errno 12] Timeout on http://archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/5/RPMS/noarch/bigtop-utils-0.7.0%2Bcdh5.2.0%2B0-1.cdh5.2.0.p0.40.el6.noarch.rpm: (28, 'Operation too slow. Less than 1 bytes/sec transfered the last 30 seconds') Trying other mirror.

Error Downloading Packages: bigtop-utils-0.7.0+cdh5.2.0+0-1.cdh5.2.0.p0.40.el6.noarch: failure: RPMS/noarch/bigtop-utils-0.7.0+cdh5.2.0+0-1.cdh5.2.0.p0.40.el6.noarch.rpm from cloudera-cdh5: [Errno 256] No more mirrors to try.

END (1) remote package bigtop-utils could not be installed, giving up

I just need to install HDFS, Hue and, of course, its dependencies. Do you know what could be the reason of the time-out error? Maybe it has something to do with the cloudera servers and that today are slow.

Also, is there any other way to install oozie's sharedlib as a workaround of this?

UPDATE:

At the time of writing this I could install the cluster, via parcels, correctly. Anyway, I would like to know the answer to this questions.

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!
