Summary: the HOST_GROUP .. <group_name> is not being substituted within the
blueprint. I am wondering why and what the correct process would be.
Details:
We see the following template substitution error (i.e. it is not performed)
in NameNode logs - which shows the blueprints are not setup/working
correctly:
2015-10-13 17:58:49,101 INFO namenode.NameNode
(NameNode.java:setClientNamenodeAddress(397)) - fs.defaultFS is
*hdfs://%HOSTGROUP::nn_1%:8020*
2015-10-13 17:58:49,103 ERROR namenode.NameNode (NameNode.java:main(1571))
- Failed to start namenode.
java.lang.IllegalArgumentException: Malformed escape pair at index 7:
hdfs://%HOSTGROUP::nn_1%:8020
Here is the first portion of our blueprints:
{
"configurations" : [
{
"core-site" : {
"properties_attributes" : {
"final" : {
"fs.defaultFS" : "true",
"ha.zookeeper.quorum" :
"%HOSTGROUP::slave_zkfc%:2181,%HOSTGROUP::slave_zk%:2181"
}
},
"properties" : {
"fs.defaultFS" : *"hdfs://%HOSTGROUP::nn_1%:8020",*
"fs.trash.interval" : "360",
Here is the hostgroup called nn_1
"host_groups" : [
{
"name" : "nn_1",
"configurations" : [ ],
"components" : [
{
"name" : "NAMENODE"
},
{
"name" : "HDFS_CLIENT"
},
.. etc
],
"cardinality" : "1"
},
So why is the substitution not occurring? Thx!
