Invoke-HDFS Cmdlet
Searches and updates HDFS data.
Syntax
Invoke-HDFS [parameters]
Remarks
The Invoke-HDFS cmdlet allows you to use SQL statements to execute any SQL statement directly. Below is the syntax for a parameterized query:
$query = Invoke-HDFS -Connection $connection -Query 'SELECT * FROM Files WHERE FileId=@FileId' -Params @{'@FileId'='119116'}
This cmdlet is also useful for executing stored procedures. Use the EXEC keyword to call a stored procedure:
$query = Invoke-HDFS -Connection $connection -Query 'EXEC Open Path = @Path' -Params @{"/user/root/test/new.txt"}
To pass multiple Params parameters, use a semicolon (;) as a delimiter. The code below outlines the structure of an EXEC command with two parameters (param1 and param2):
$query = Invoke-HDFS -Connection $connection -Query 'EXEC MyStoredProc Input1=@param1, Input2=@param2' -Params @{'@param1' = 'value1'; '@param2' = 'value2'}
