Dear Eric The Brave,
As per the wiki:"znodes are limited to the amount of data that they can
have. ZooKeeper was designed to store coordination data: status information,
configuration, location information, etc. This kind of meta-information is
usually measured in kilobytes, if not bytes. ZooKeeper has a built-in sanity
check of 1M, to prevent it from being used as a large data store, but in
general it is used to store much smaller pieces of data."
See:
https://cwiki.apache.org/confluence/display/ZOOKEEPER/ProjectDescription
Also:"jute.maxbuffer: (Java system property: jute.maxbuffer)
This option can only be set as a Java system property. There is no zookeeper
prefix on it. It specifies the maximum size of the data that can be stored
in a znode. The default is 0xfffff, or just under 1M. If this option is
changed, the system property must be set on all servers and clients
otherwise problems will arise. This is really a sanity check. ZooKeeper is
designed to store data on the order of kilobytes in size."

Subject: Custom Jars for a config in the Solr Cloud world..
I've got a Solr instance with a number of cores that are each configured by
upload the configuration information to ZooKeeper. The newest index needs
the UIMA jars. Normally I would put them in the core's /lib directory, but
since I am only accessing my server via ZooKeeper, I don't have that
directory as an option.
I know I could manually upload the jars onto the server, and then put some
sort of path to them, but I'm hoping to manage all uploading of core
specific configurations (and jars) via ZooKeeper. I'm wondering if I am
missing something in this new ZooKeeper enabled world....? Just for fun,
I'm going to try and put the ~ 2 MB worth of Jars inside my /conf/ directory
and then upload through ZooKeeper to see what happens.
Eric
