Same as hive.metastore.consider.immediate.sql, for go through statements in just a transaction that modifies metastore details. As a result of non-standard actions in Postgres, if a direct SQL choose query has incorrect syntax or one thing related within a transaction, your complete transaction will fail and tumble-again to DataNucleus won't be possible. You should disable the use of direct SQL within transactions if that happens within your scenario.
Whether to check, convert, and normalize partition benefit specified in partition specification to conform into the partition column type.
LDAP connection URL(s), value could be a SPACE separated list of URLs to a number of LDAP servers for resiliency. URLs are tried using from the order specified until finally the link is effective.
Same as hive.metastore.test.immediate.sql, for read statements within a transaction that modifies metastore data. Because of non-conventional conduct in Postgres, if a immediate SQL select query has incorrect syntax or something comparable within a transaction, your complete transaction will fail and drop-back to DataNucleus won't be probable. You must disable the utilization of immediate SQL within transactions if that comes about inside your situation.
Adjustment to mapjoin hashtable sizing derived from table and column statistics; the estimate of the volume of keys is divided by this benefit. If the worth is 0, statistics are certainly not applied and hive.hashtable.initialCapacity is utilised instead.
Both the location of a HiveServer2 world-wide init file or possibly a Listing that contains a .hiverc file. If the house is ready, the worth has to be a legitimate route to an init file or Listing in which the init file is found.
Set this to accurate if desk directories must inherit the permissions on the warehouse or database Listing as an alternative to currently being produced with permissions derived from dfs umask.
Irrespective of whether to push a limit by means of still left/suitable outer sign up for or union. If the worth is accurate and the dimensions with the outer enter is lessened enough (as specified in hive.
Establishes if, in the event the prefix of the key used for intermediate statistics selection exceeds a specific size, a hash of The crucial element is applied instead. If the worth < 0 then hashing is rarely utilised, if the value >= 0 then hashing is used only once the important prefixes' duration exceeds that worth.
Optimum quantity of entries within the vector Team BY aggregation hashtables. Exceeding this will induce a flush no matter memory strain issue.
When hive.optimize.limittranspose is legitimate, this variable specifies the nominal share (fractional) reduction on the size with the outer enter on the sign up for or input with the union that the optimizer need to get to be able to implement the rule.
This location reflects how HiveServer2 will report the desk types for JDBC and various consumer implementations that retrieve the out there tables and supported table sorts.
Whether the Hive metastore ought useful link to try to use direct SQL queries rather than the DataNucleus for selected study paths. This tends to enhance metastore effectiveness when fetching numerous partitions or column statistics by orders of magnitude; even so, it is not certain to work on all RDBMS-es and all versions.
configured with embedded metastore. To get best efficiency, established config to satisfy the subsequent problem
