If ORC reader encounters corrupt information, this price will likely be made use of to determine no matter if to skip the corrupt info or throw an exception. The default actions is always to toss an exception.
Moreover the configuration Houses mentioned In this particular section, some Qualities in other sections may also be connected with ORC:
If this is set to true, mapjoin optimization in Hive/Spark will use statistics from TableScan operators at the basis in the operator tree, in lieu of guardian ReduceSink operators in the Be a part of operator.
This house is used in LDAP search queries when finding LDAP group names that a specific consumer belongs to. The value in the LDAP attribute, indicated by this house, should be a complete DN for your consumer or perhaps the short username or userid.
The string which the regex will likely be matched against is of the subsequent kind, exactly where ex is actually a SQLException:
If That is set to legitimate, mapjoin optimization in Hive/Spark will use supply file dimensions associated with the TableScan operator on the foundation with the operator tree, as opposed to making use of operator statistics.
This parameter decides if Hive ought to include yet another map-lessen career. In the event the grouping set cardinality (4 in the instance earlier mentioned) is greater than this value, a new MR task is additional beneath the assumption that the orginal "team by" web link will reduce the knowledge measurement.
Whether or not to eliminate the union and thrust the operators in between union along with the filesink earlier mentioned union. This avoids an extra scan of your output by union.
Decides if, in the event the prefix of The real key employed for intermediate statistics assortment exceeds a particular duration, a hash of The crucial element is made more tips here use of as an alternative. If the worth < 0 then hashing is rarely applied, if the value >= 0 then hashing is employed only when the critical prefixes' duration exceeds that worth.
This property is to indicate what prefix to utilize when creating the bindDN for LDAP link (when making use of just baseDN). So bindDN will be "=,". If userDNPattern and/or groupDNPattern is used in the configuration, the guidKey is not essential. Largely essential when just baseDN is getting used.
Determines the selection system employed by metastore consumer to hook up with distant metastore. SEQUENTIAL implies that the very first valid metastore within the URIs specified as Portion of hive.metastore.uris are going to be picked. RANDOM implies that the metastore will likely be picked randomly.
Using this regex as opposed to updating the original regex for hive.security.authorization.sqlstd.confwhitelist indicates which you can append for the default which is set by SQL regular authorization as opposed to changing it solely.
Part of whole memory to be used by map-aspect team aggregation hash desk, when this team by is followed by map sign up for.
To show on Hive transactions, change the values of those parameters from their defaults, as explained underneath:
