Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for chan=
ge notification.

The "SolrCloud" page has been changed by Tom=C3=A1s Fern=C3=A1ndez L=C3=B6b=

Comment:
Added documentation on how to use Zookeeper chroot with Solr

  {{{
  sh zkcli.sh -cmd linkconfig -zkhost 127.0.0.1:9983 -collection collection=
1 -confname conf1 -solrhome example/solr
  }}}
+ =3D=3D=3D Zookeeper chroot =3D=3D=3D
+ If you are already using Zookeeper for other applications and you want to=
 keep the ZNodes organized by application, or if you want to have multiple =
separated SolrCloud clusters sharing one Zookeeper ensemble you can use Zoo=
keeper's "chroot" option. From Zookeeper's documentation: http://zookeeper.=
apache.org/doc/r3.3.6/zookeeperProgrammers.html#ch_zkSessions
+ {{{
+ An optional "chroot" suffix may also be appended to the connection string=
. This will run the client commands while interpreting all paths relative t=
o this root (similar to the unix chroot command). If used the example would=
 look like: "127.0.0.1:4545/app/a" or "127.0.0.1:3000,127.0.0.1:3001,127.0.=
0.1:3002/app/a" where the client would be rooted at "/app/a" and all paths =
would be relative to this root - ie getting/setting/etc... "/foo/bar" would=
 result in operations being run on "/app/a/foo/bar" (from the server perspe=
ctive).
+ }}}
+ To use this Zookeeper feature, simply start Solr with the "chroot" suffix=
 in the zkHost parameter. For example:
+ {{{
+ java -DzkHost=3Dlocalhost:9983/foo/bar -jar start.jar
+ }}}
+ or
+ {{{
+ java -DzkHost=3Dzoo1:9983,zoo2:9983,zoo3:9983/foo/bar -jar start.jar
+ }}}
+ '''NOTE:''' With Solr 4.0 you'll need to create the initial path in Zoook=
eeper before starting Solr. Since Solr 4.1, the initial path will automatic=
ally be created if you are using either ''bootstrap_conf'' or ''boostrap_co=
nfdir''.
  =3D=3D Known Limitations =3D=3D
  A small number of Solr search components do not support distributed searc=
h. In some cases, a component may never get distributed support, in other c=
ases it may just be a matter of time and effort. All of the search componen=
ts that do not yet support standard distributed search have the same limita=
tion with SolrCloud. You can pass distrib=3Dfalse to use these components o=
n a single SolrCore.
