I encountered this error while performing a Presto query on Alluxio. What does this timeout mean, and how can I fix it?




com.facebook.presto.spi.PrestoException: Error opening Hive split alluxio://xxxxx:19998/s3/data/m-00020 (offset=134217728,

          You will receive this error when the Alluxio worker takes too long (configurable through alluxio.user.network.netty.timeout) to provide data to the client.



          One simple workaround is to increase timeout.



          However, this is generally a symptom of the worker being overloaded in some way. Common things to check in your setup:




          1. Alluxio worker load, possibly a problem if your compute is co-located and there is no resource management

          2. Alluxio worker to under file system load/bandwidth, this is often a bottleneck for remote storages like object stores.


          If these are bottlenecks, you can try reducing the concurrency or increasing the number of nodes in your cluster.

                    How to change which sound is reproduced for terminal bell?

                    Image
                    3 Recently upgrade to 18.10 from 18.04, and using the terminal is becoming annoying: the new alert sound is a drip ( /usr/share/sounds/gnome/default/alerts/drip.ogg ), and the previous one is still located at ( /usr/share/sounds/ubuntu/stereo/bell.ogg ). My issue is that at the gnome-terminal, when autocompleting or pressing left BOTH sounds are reproduced, at the same time. I want to just have ubuntu/stereo/bell.ogg active, not both . At the moment I have been only able to reduce the volume of the alerts (but still both are played), or turn the alerts down (but I dislike both "solutions"). gnome-terminal 18.10 teminal-bell share | improve this question

                    Title Spacing in Bjornstrup Chapter, Removing Chapter Number From Contents

                    up vote 5 down vote favorite 2 I would like to make it so that the vertical space below the title of each chapter is the same when using the Bjornstrup package (i.e. so that the descenders do not affect the spacing - as shown by the red arrow in the picture below). I think I'm fairly happy with the spacing around "A chapter", so I'd really like titles without descenders (e.g. "Contents") to have the same vertical spacing as "A chapter" below the title. I would also like to remove the large "0" in the contents title.
