first method to find the default configuration is best because each attribute is described and can be used directly. In addition, Core-site.xml is a global configuration, and Hdfs-site.xml and mapred-site.xml are local configurations for HDFs and mapred respectively. 2 common port configurations 2.1 HDFs Port Parameters Describe Default Configuration file Example value Fs.default.name Namenode Namenode RPC Interactive port

Background: The data type of some fields in the Hive table has been modified, such as from String-> Double, at which point the underlying file format for the table is parquet, after the modification, the Impala index is updated, and then the fields that modify the data type appear with the Parquet Problem with schema column data type incompatibility. such as: impala-- Extracting results for the following error: Bad status for Request Tfetchresultsreq (fetchtype=0, Operationhandle=toperationhan

least one, but probably all, of your mappers is unable toFindA jar they need. That means this either the jar does not exist or the user trying to access them does does have the required permissions. First checkifThefileexists by running Hadoop FS-lshome/sqoopuser/sqoop-1.4.3-cdh4.4.0/sqoop-1.4.3-cdh4.4.0. jar by a user with Superuser privileges on the cluster. If It does not exist, put it there with Hadoop fs-put {jarlocationon/namenode/filesystem/sqoop-1.4.3-cdh4.4.0. jar}/home/sqoopuser/sqoop

thread, thread1, and thread2 print results are 3,2,2 respectively.The last 6 lines of print illustrate the fact that local variables declared as thread_local persist in the thread, unlike the life cycle of a normal temporary variable, which has the same initialization characteristics and life cycle as a static variable, although it is not declared Static. In the example, the thread_local variable i in the Foo function is initialized at the first execution of each thread and is released at the e
