Review request for Ambari, Oliver Szabo and Robert Levas.
Bugs: AMBARI-15454
https://issues.apache.org/jira/browse/AMBARI-15454
Repository: ambari
Description
-------
hBlueprint install using config_recommendation strategy seems to hang for a
long time (couple of hours?) and ends up logging exceptions continually to
ambari-server.log. At the same time many hundreds of directories are seen
getting created under /var/run/ambari-server/stack-recommendations (I have seen
above 800-900). If you keep it running eventually the cluster install seems to
start but fails miserably at least during the start and some of it makes
obvious that configuration recommendations were NOT applied. You see errors
during startup that hint that options used for JVM (For Datanode etc) were
unreasonable.
Note that both the blueprint and cluster templates used empty configurations.
Example:
.
.
"configurations" : [],
"host_groups": [
{
"name": "host-group-1",
"configurations" : [],
"cardinality" : "1",
"components": [
{ "name": "APP_TIMELINE_SERVER" },
{ "name": "DATANODE" },
{ "name": "FALCON_CLIENT" },
{ "name": "FALCON_SERVER" },
{ "name": "FLUME_HANDLER" },
{ "name": "HBASE_CLIENT" },
{ "name": "HBASE_MASTER" },
{ "name": "HBASE_REGIONSERVER" },
.
.
.
Teh cluster template was:
{
"blueprint": "1node",
"config_recommendation_strategy" : "ONLY_STACK_DEFAULTS_APPLY",
"default_password": "myPassword1",
"host_groups": [
{
"name": "host-group-1",
"hosts": [
{
"fqdn": "mynode.ibm.com"
}
]
}
]
}

Testing
-------
1) ambari-server unit tests
Results :
Tests run: 3968, Failures: 0, Errors: 0, Skipped: 33
2) Added unit test to
ambari-server/src/test/java/org/apache/ambari/server/controller/internal/BlueprintConfigurationProcessorTest.java
