This is only A data and the one large csv will complete > correctly but passing in the directory of part files will exhibit the error. > The data is identical except in the number of files that are used to contain > the data. > The error occurs using the local raw filesystem and with master = local and > is pretty fast to reach. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
