Subject [jira] [Commented] (HADOOP-14026) start-build-env.sh: invalid docker image name
Date Thu, 26 Jan 2017 17:53:24 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15840126#comment-15840126
] 

Allen Wittenauer commented on HADOOP-14026:
-------------------------------------------

bq. not contains any non-english characters

That's a violation of POSIX: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_437
which references http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_278
.

bq. nor any upper case english characters

it's easier then to just pass it through tr.

> start-build-env.sh using the current user name to generate a docker image name. But the
current user name can contains some not english characters and upper letters (after all this
is usually the name/nickname of the owner). Both of them are not supported in docker image
names, so the script will fail.
