Igor Motov	21ed6bb90c	Core: Don't allow indices containing too-old segments to be opened ... When index is introduced into the cluster via cluster upgrade, restore or as a dangled index the MetaDataIndexUpgradeService checks if this index can be upgraded to the current version. If upgrade is not possible, the newly upgraded cluster startup and restore process are aborted, the dangled index is imported as a closed index that cannot be open. Closes #10215	2015-05-19 23:37:05 -04:00
Michael McCandless	399f0ccce9	Core: add only_ancient_segments to upgrade API, so only segments with an old Lucene version are upgraded ... This option defaults to false, because it is also important to upgrade the "merely old" segments since many Lucene improvements happen within minor releases. But you can pass true to do the minimal work necessary to upgrade to the next major Elasticsearch release. The HTTP GET upgrade request now also breaks out how many bytes of ancient segments need upgrading.
