When

cluster

via

Ambari
...
on

hosts

that

already

have

bits

installed
...
(including
...
an

existing

cluster

deployed
...
via

Ambari),
...
perform

the

following:
...
- Stop
...
- all
...
- the
...
- services
...
- on
...
- all
...
- the
...
- nodes(including
...
- ganglia
...
- and

...
- It
...
- is
...
- also
...
- a

- good
...
- practice
...
- to

- delete
...
- the

- rpms
...
- from

HTTP error 400 – Bad Request – during REST call (POST, PUT, DELETE) to Ambari server
Ambari Server now expects an additional HTTP header called "X-Requested-By" for all non-GET calls. The value can be set to anything. For example:
| Code Block |
|---|
curl -i -H 'X-Requested-By: mycompany' -X POST -d '{"Clusters": {"version": "HDP-2.0.6"}}' --user admin:admin http://hadoop1.mycompany.com:8080/api/v1/clusters/cluster1 |
#Spaces in manager DN/Base DN causing login issues in AmbariAnchor Spaces in manager DN/Base DN causing login issues in Ambari Spaces in manager DN/Base DN causing login issues in Ambari
Note that there are some issues with Ambari current release 1.2.5 in case you have spaces in baseDN/managerDN. Please take a look at: https://issues.apache.org/jira/browse/ambari-3006.
...
The
...
fix
...
will
...
be

available
...
in
...
1.4.1

release

of

Ambari.

I
...
have
...
created
...
a
...
jar
...
with
...
the
...
patch
...
applied
...
on
...
top
...
of
...
branch-1.2.5.
...
The
...
jar
...
is
...
posted
...
at
...
http://people.apache.org/~mahadev/ambari/ambari-server-1.2.5.17.jar.
...
Download
...
the
...
above
...
jar
...
and
...
follow
...
the
...
following
...
steps
...
for
...
fixing
...
the
...
issue:
...
- Stop
...
- ambari
...
- server
...
- using
| Code Block |
|---|
{code} ambari-server stop {code} * Replace the ambari server jar with the downloaded jar {code} cp <download |
- Replace the ambari server jar with the downloaded jar. Please backup the ambari-server jar before you overwrite in case you run into issues.
| Code Block |
|---|
cp <downloaded_ambari_server_jar> /usr/lib/ambari-server/ambari-server-1.2.5.17.jar {code |
- Restart Ambari Server
| Code Block |
|---|
} * Restart Ambari Server {code} ambari-server start {code} |
This
...
should
...
fix
...
the

issue

with
