We have pending open files on a regular basis since we search while
relocating etc. and keep search contexts around that are cleaned up
later. We should rather let the close call pass on even if files are
open and only force failures on teardown in ElasticsearchIntegrationTest
Currently when importing projects into eclipse you need to run 'mvn
eclipse:eclipse' on the command line to generate the poject files. This
means that when the pom changes you need to re-run the command on the
command line to reflect those changes in the project in eclipse. This
commit allows the developer to import the project as an existing maven
project (can be shared using git after import) and then allows the
application to be run inside eclipse using the .launch file in
/dev-tools enabling easy debugging of the application within eclipse
without requiring a maven build.
When starting elasticsearch with a wrong linux user, it could generate a `NullPointerException` when `PluginsService` tries to list available plugins in `./plugins` dir.
To reproduce:
* create a plugins directory with `rwx` rights for root user only
* launch elasticsearch from another account (elasticsearch for example)

Closes#4187.
1) add build_desc property variable
2) use build_id plus build_number as an unique file name
3) tools subdirectory should be under current PWD when the script is
executing
Add FieldDataTermsFilter that compares terms out of
the fielddata cache. When filtering on a large
set of terms this filter can be considerably faster
than using a standard lucene terms filter.
Add the "fielddata" execution mode to the
terms filter parser to enable the use of
the new FieldDataTermsFilter.
Add supporting tests and documentation.
Closes#4209
