Scott Creeley commented on AMBARI-5194:
---------------------------------------
suggested improvements:
1. existing users and directories created during RHS GlusterFS install - test
for existence of gluster and then if found follow the existing suppressed
control block
# see if /var/lib/amabari-agent/data/HDP-*.Gluster* exists OR if
/mnt/glusterfs exists
# we can assume rhs/gluster is being used or was once used
REPO_ARTIFACT_PATH = "/var/lib/ambari-agent/data/"
REPO_ARTIFACT_FILE = "HDP-*.Gluster"
REPO_ARTIFACT_SEARCH = "%s%s" % (REPO_ARTIFACT_PATH,REPO_ARTIFACT_FILE) +
"*"
gluster_artifact_result = glob.glob(REPO_ARTIFACT_SEARCH)
GLUSTER_FS_PATH = "/mnt/glusterfs"
gluster_fs_result = glob.glob(GLUSTER_FS_PATH)
isGluster = gluster_artifact_result != [] or gluster_fs_result != []
if componentsMapped or commandsInProgress or isSuse or isGluster:
dict['existingRepos'] = [self.RESULT_UNAVAILABLE]
dict['installedPackages'] = []
dict['alternatives'] = []
dict['stackFoldersAndFiles'] = []
dict['existingUsers'] = []
else:
etcs = []
2. iptables improvement - change command to iptables -S. Cleaner output that
can be verfied easily to show iptables have been flushed
def checkIptables(self):
iptablesIsRunning = True
try:
iptables = subprocess.Popen(["iptables", "-S"], stdout=subprocess.PIPE)
stdout = iptables.communicate()
if stdout == ('-P INPUT ACCEPT\n-P FORWARD ACCEPT\n-P OUTPUT ACCEPT\n',
None):
iptablesIsRunning = False
except:
pass
dict['iptablesIsRunning'] = self.checkIptables()
> Improve User Experience during install

> Key: AMBARI-5194
> URL: https://issues.apache.org/jira/browse/AMBARI-5194
> Project: Ambari
> Issue Type: Improvement
> Components: agent
> Affects Versions: 1.4.4
> Environment: Red Hat Storage Server - GlusterFS stack
> Reporter: Scott Creeley
> Labels: Ambari, HostCheck
> Fix For: 1.5.0
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> improve the HostInfo.py (Host Check) during the ambari installer process,
> particularly for step 3 of the process where the nodes are registered and
> confirmed. The check will find some user and directories that are normal for
> a RHS GlusterFS cluster, and we think they should be suppressed to help
> improve overall user experience. Also, the iptables check always returns a
> 0, even when the iptables have been flushed, again this results in an
> erroneous warning message.
