stack commented on HBASE-15082:
-------------------------------

Docker failed to install spellcheck (it must know who is writing the patch if 
it is pulling that package)

/tmp/ShellCheck-0.4.2-8/ShellCheck-0.4.2/Setup.hs, 
/tmp/ShellCheck-0.4.2-8/ShellCheck-0.4.2/dist/setup/Main.o )

/tmp/ShellCheck-0.4.2-8/ShellCheck-0.4.2/Setup.hs:15:25:
    Module `System.Process' does not export 
`callCommand'
Failed to install ShellCheck-0.4.2
cabal: Error: some packages failed to install:
ShellCheck-0.4.2 failed during the configure step. The exception was:
ExitFailure 1
The command '/bin/sh -c cabal update && cabal install shellcheck --global' 
returned a non-zero code: 1

Let me retry. See if transitory.
