MySQL Daemon failed on the start of docker version of HDP 2.6.4

I am just starting with a Hortonworks tools and using Docker version of HDP 2.6.4 Sandbox on the Ubuntu 16.04.2 LTS server.

Fore some reason MySQL fails immediately after running of the start-sandbox-hdp-standalone_2-6-4.sh with the message

MySQL Daemon failed to start.

What might be the reason?

I see that there are some minor difference between the "start_sandbox-hdp.sh" script in previous and current version. Can you please try using the

Difference in old "start_sandbox-hdp.sh":

Can you please try using the following Script "start_sandbox-hdp.sh" instead and see if it works:

Thank you for your message.

Unfortunately the same result. I'm steel getting the same MySQL daemon error.

I have also tried this with HDP 2.6.1 docker image version.

'service mysqld start' failed with the same message:

MySQL Daemon failed to start.
Starting mysqld:  			[FAILED]

'/var/lib/mysql' permissions:

drwxr-xr-x 1 mysql mysql 4096 Feb  1 10:54 /var/lib/MySQL

There are no content lines in the '/var/log/mysqld.log':

[root@sandbox-hdp log]# cat /var/log/mysqld.log
[root@sandbox-hdp log]#

@Timur Kobilov

Since the logs are empty, you could run the command as follows to generate a more verbose output.

sh -x /etc/init.d/mysqld start

The timestamp on the mysql folder is Feb 1 which is confusing.

Could you please redeploy HDP 2.6.4 with the script downloaded from here ?

The md5sum of the downloaded script should be b14f4538147851c51b26d9da37ab931c. Please verify the same after download.

So... I afraid I'm missing something...

I got 'start-sandbox-hdp-standalone_2-6-4.sh.zip', unzipped it and deployed HPD 2.6.4 as discribed here

The md5sum of the 'start-sandbox-hdp-standalone_2-6-4.sh.zip' was 2c2cee0aafc71405b373f89eb9a988d7 as on the picture below (not b14f4538147851c51b26d9da37ab931c):

Starting this script leads to the same 'MySQL Daemon failed to start' message as before. Timestamp of the '/var/lib/mysql' is Feb 1:

62700-2018-03-07-16-05-14.png

I also tried 'sh -x /etc/init.d/mysqld start'. The output is here

@Timur Kobilov

It looks like the script you have is not the proper one.

Could you please download from the link here.

Click on "DOWNLOAD FOR DOCKER LINUX/MAC" . It is not a zipped file but just a shell script named "start-sandbox-hdp-standalone_2-6-4.sh" and having an md5sum of "b14f4538147851c51b26d9da37ab931c"

The details can be found here in the release notes.

Please try deploying using the same and let us know if you have issues.
