-------------------------------
On Katta slave node, my folder hierarchy is:
|/var/data|root|
|/var/data/hadoop|store hadoop data|
|/var/data/hdfszips|store zip tmp data, which get from hdfs,then move to
katta's shardes|
|/var/data/solr|root store solr core configures|
|/var/data/solr/seoproxy|store seoproxy's solr config,which is used by
sub-proxy|
|/var/data/katta/shards/nodename_20000/seo0#seo0|store seo0 shard,which is
deployed from master node|
|/var/data/zkdata|store zkserver data,which is zk logs and snapshotes|
On Katta master node, my folder hierarchy is:
|/var/data|root|
|/var/data/hadoop|store hadoop data|
|/var/data/hdfsfile|store solr tmp data, which get from solr dataimporter,then
zip && put to hdfs|
|/var/data/solr|root store solr core configures|
|/var/data/solr/seo|store seo's solr config,which is used by tomcat's webapp|
|/var/data/zkdata|store zkserver data,which is zk logs and snapshotes|
so, my config is from five folderes:
|Master|/var/data/solr/seo|tomcat webapp's solrcore config|
|Slave|/var/data/solr/seoproxy|sub-proxy's solrcore config|
|Master|/var/data/hdfsfile|query-core's config,which is config template|
|HDFS|http://hdfsname:9000/seo/seo0.zip|query-core seo0's zip file,which is
hold conf|
|Slave|/var/data/katta/shards/nodename_20000/seo0#seo0/conf|query-core seo0's
config,which is unzipped from seo0.zip of HDFS|
and, /var/data/hdfsfile structure is:
{noformat}
seo@seo-solr1:/var/data/hdfsfile$ ll
