In order to process the main dataset, there is a certain amount of extra read-only data required. This data is known as side data. There are two categories of side data distribution techniques:
Via the job configuration: This method is only a viable option when the data size is small (in kilobytes). Exceeding this threshold may put unnecessary pressure on the memory usage of the Hadoop daemons especially. This is especially the case when a lot of jobs are running.
Via distributed cache - Hadoop has a distributed cache mechanism which is a better option than serializing side data using job configuration.

What is abnormal distribution?
A standard distribution regards 95% of all data being within 2-standard deviations of either side. Similarly, within one standard deviation either way is 68% of all data. This creates a bell curve distribution. An abnormal distribution would be erratic and not follow such a statistical structure of representation.
What distribution that has a great number of values on one side?
The answer depends on one side of WHAT! There is no distribution which has a greater number of values on either side of its median.
What does a skewness of 1.27 mean?
A skewness of 1.27 indicates a distribution that is positively skewed, meaning that the tail on the right side of the distribution is longer or fatter than the left side. This suggests that the majority of the data points are concentrated on the left, with some extreme values on the right, pulling the mean higher than the median. In practical terms, this might indicate the presence of outliers or a few high values significantly affecting the overall distribution.
What is skewness how would you find it in a non symmetrical distribution?
Skewness is a measure of the extent to which the probability distribution of a random variable lies more to one side of the mean, as opposed to it being exactly symmetrical.If μ and s are the mean and standard deviation of a random variable X, thenSkew(X) = Expected value of [(X - μ)/s]3
Why is a bell curve used?
Bell curves are used because they represent an exactly normal distribution. A normal distribution means that all of the values are centered around a single mean value, with the probability density decreasing equally on either side of the mean. This is the distribution that is most widely used in statistics because it is often found naturally (truly random data follows a normal distribution), and also because it follows from the central limit theorem.
What is symmetric distribution?
It is a probability distribution in which the probability of the random variable being in any interval on one side of the mean (expected value) is the same as for the equivalent interval on the other side of the mean.
How do you place main and distribution bars in slab?
Main bars are placed parellel to shor and distribution along longer side
Which side of a CD contains the data?
the shiny side/smaller ring inside has the data coz u could put a cover on the other side
Does the printed side of a CD contain data?
No the side with the data is the non printed side simply because there is less for the read/write head of the drive to see through when moving data onto or off the disk
What is the physical distribution side of marketing?
Physical distribution is one of the largest arenas of marketing and has been defined as the analysis, planning, and control of activities concerned with the procurement and distribution of goods.
What is higher skewness?
Higher skewness indicates a greater asymmetry in the distribution of data points around the mean. A positive skew means that the tail on the right side of the distribution is longer or fatter, while a negative skew indicates the opposite, with a longer or fatter left tail. In practical terms, higher skewness can suggest potential outliers and may affect statistical analyses that assume a normal distribution.
