@Praveen Atmakuri I want to ensure the document in the link above will move your on-premise MySQL to MySQL in Azure.Azure Database for MySQL is a Microsoft cloud based service based on the MySQL Community Edition database engine. Advantages Built-in high availability with no additional cost. Predictable performance, using inclusive pay-as-you-go pricing. Scale as needed within seconds. Secured to protect sensitive data-at-rest and in motion. Automatic backups and point-in-time-restore for up to 35 days. Enterprise-grade security and compliance. Difference between Azure MSSQL and Azure MySQL DB MySQL is open source while MSSQL is licensed(commercial). MySQL supports more programming languages than MSSQL MySQL supported several Platforms Windows, Linux and Mac OS while MSSQL runs exclusively on windows though Microsoft recently announced MSSQLwill be available on Linux. MySQL supports a number of storage engines. While using MySQL even have option to use a plug-in storage engine. MySQL does not allow users to kill or cancel a query when it is running But SQL Server programmers can truncate a database query during execution without killing the entire process. These are just but a few distinct differences between the 2 RDBMS's If you found this answer addressed your question, please take a moment to log in and click the "accept" link on the answer.

Thank you @Geoffrey Shelton Okot It helps. Actually, I was thinking it will create a user in CentOS only. But It has created a user in HDFS as well.

@RAUI Yes there is another way of achieving this. You can use the method copy() from the FileUtil class and pass your FileSystem object to it to effectively copy your files from the source HDFS location to the target. As with using rename() you will need to ensure you target directory is created before calling copy. FileUtil.copy() has a signature where you provide a source and destination FS and in this case you would provide the same FS object since you are looking to copy files to a different location on the same HDFS. There is also a boolean option to delete the source file after the copy if that fits your use case. Here is a link to the FileUtil API: http://hadoop.apache.org/docs/r2.8.0/api/org/apache/hadoop/fs/FileUtil.html

@Gaurav Sharma I think I figured it out. When you asked me to check zoo.cfg, I noticed there were a block of ports ZK communicates over server.1=hdp.c.my-project-1519895027175.internal:2888:3888 server.2=slave1.c.my-project-1519895027175.internal:2888:3888 server.3=slave2.c.my-project-1519895027175.internal:2888:3888 In GCP, you have to configure the firewall manually (or that's what I'm doing at least). Once I added that range of ports to the firewall, I restarted the ZK servers and most of my services work now! I say most, because Spark2 History Server and Zeppelin still aren't working. But I'll open another thread for those.
