问题 I'm working with Ubuntu 12.04 LTS. I'm going through the hadoop quickstart manual to make a pseudo-distributed operation. It seems simple and straightforward (easy!). However, when I try to run start-all.sh I get: localhost: Error: JAVA_HOME is not set.

Ensuring that my program is not doing a concurrent file write

由 一曲冷凌霜 提交于 2019-11-27 07:11:43
问题 I am writing a script that is required to perform safe-writes to any given file i.e. append a file if no other process is known to be writing into it. My understanding of the theory was that concurrent writes were prevented using write locks on the file system but it seems not to be the case in practice. Here's how I set up my test case: I am redirecting the output of a ping command: ping 127.0.0.1 > fileForSafeWrites.txt On the other end, I have the following python code attempting to write

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago .

I am using a Beaglebone Black with Ubuntu and OpenCV 2.4.8. I've experimenting with SURF, ORB, SIFT, Moments, and BFMatcher. I haven't found a reliable way to determine the orientation of an arrow.
