PHP artisan cache: clear command reports an error

Use the clear cache command when building projects with laravel version 5.7 or above:

php artisan cache:clear  

Sometimes, the following errors are reported:

“Failed to clear cache. Make sure you have the appropriate permissions”

The reason is that there are two directories. You need to create a new directory.

mkdir -p storage/framework/cache/data

You also need to set directory permissions  

chmod 777 /home/www/dir/bootstrap/cache && amp; chmod 777 /home/www/dir/bootstrap/cache/*

Sqoop exports hive data to MySQL Error [How to Solve]

The following error is reported when exporting hive data from sqoop to MySQL

Export job failed!
	at org.apache.sqoop.mapreduce.ExportJobBase.runExport(ExportJobBase.java:445)
	at org.apache.sqoop.manager.SqlManager.exportTable(SqlManager.java:931)

	at org.apache.sqoop.Sqoop.runTool(Sqoop.java:243)
	at org.apache.sqoop.Sqoop.main(Sqoop.java:252)

This problem is caused by the field type problem or table structure problem between MySQL and hive (the fields are different or the table structure is different).

Solution: modify the type in MySQL table to be the same as that in hive table or modify the table structure
