>             Project: IMPALA
>          Issue Type: Bug
>          Components: Catalog, Distributed Exec
>    Affects Versions: Impala 2.8.0
>            Reporter: Krishna Thirumalasetty
>            Priority: Critical
> We are running CDH 5.10.1 with Impala.  While executing "alter table <table-name>
recover partitions; - we get "Error communicating with impalad: TSocket read 0 bytes" error
message. After repeated attempts to recover the table partitions, we were finally able to
recover the partitions. At which point, we ran "compute stats <table-name>;" and received
this error message: CatalogException: Table was modified during stats computation.
> Although both these errors may be mutually exclusive, somehow they seems to only happen
on the two tables with over 10,000 partition files.
> Please let me know, if anyone has any ideas on how to resolve this issue.
